Patent Description:
The internet uses ubiquitous protocols TCP/IP and UDP/IP over Ethernet. The main features of these protocols are standardized peering, routing, handling of, and the sending or relaying data packets from one point to another. A global virtual network is an over-the-top (OTT) construct laid over the internet. A network tapestry weaves multiple different network fabrics together into a tapestry.

Slingshot is a transport mechanism between known points sending unlimited sized data files over long distances utilizing remote direct memory access (RDMA) to write files to remotely located parallel file system (PFS) devices over InfiniBand (IB) over distance or equivalent network type which can send files via RDMA over distance through a fiber back bone. In the example of using IB, its IB switches and IB devices at either end of a fiber line constitute the physical plumbing layer on top of which Slingshot operates. Other network types may need other types of end-point devices at either end of the line.

The granularity of a tick governs the timing synchronization and time interval period which coordinates sling activity. Data Beacon Pulser (DBP) is a technology which utilizes Slingshot to send a constant stream of pulses of information from one region to one or more other regions. Slinghop is a technology which integrates as a network segment within an existing IP pathway of segments, and it uses Slingshot as a transport technology over long distances to reliably speed up transfer.

There are various drawbacks associated with prior art technologies. The internet is a network of networks built specifically to robustly address peering issues, congestion, routing inefficiencies, and other impediments to traffic flow across various network boundaries, and constriction points through various peering points. Hops across joint points of two segments are subject to a delay due to the inherent limitations of the internet protocol. IP is a store and forward model where a packet is received in its entirety before being passed on adding a tiny time delay through each device. A global virtual network (GVN) runs over-the-top (OTT) of the internet or other network fabrics, and it offers advantages, but it still must contend with the core problem of IP inefficiency over distance. While InfiniBand (IB) is a cut-through network model, is fast and is parallel, one limitation is its point to point topology for IB over distance. Slingshot to a PFS cluster or device in a remote region addresses the speed and reliability problems mentioned above for long-haul IP traffic. However, there remains a need to efficiently route Slingshot traffic to a specific region, at a certain quality of service (QoS), and to assert other control over routing, while concurrently routing other traffic to other regions with the same degree of control.

Patent document <CIT> describes a system for facilitating remote access to parallel file system in a network using privileged kernel mode and unprivileged user mode to avoid processing failure.

Slingroute or Slingrouting is the name for various related methods to route the sending of data "files" via slingshot from one region to another region based on the choice of target parallel file system (PFS) device and other options.

Slingshot at the physical layer makes all PFS devices reachable and addressable. Therefore, Slingshot to a specific PFS which is coupled with a sling node (SLN) and/or backbone exchange server (SRV_BBX) in a target region forms the basis of routing. Each access point server (SRV_AP) can send traffic to any other SRV_AP via Slingshot. Each access point server (SRV_AP) can receive traffic from any other SRV AP via Slingshot.

Direct write and load balanced write to PFS ensure high availability and failover. <FIG> describes multiple Sling nodes (SLN) at each node, with multiple PFS devices. High availability is also achieved with multiple PFS device instances and cluster options where SLNs can reach some or all PFS devices. An SLN can also send results to multiple SRV_BBX for load balancing and failover.

Sling availability module operating on a central control server (SRV_CNTRL) receives reports about each PFS, SLN, SRV_BBX, connectivity, and other elemental devices which constitute a Slingshot mechanism. The sling availability module evaluates the report data and determines which devices are over-utilized, which are under-utilized, those that are not available due to maintenance or malfunction, or other related events. It further ranks which devices are contextually available to other devices so that availability lists are catered in such a way for maximum benefit of its user as well as anticipating and addressing potential issues which can otherwise occur by randomly assigning for devices to arbitrarily jump to random devices.

Sling availability module reports on SRV_CNTRL also offers a real-time understanding of load, historical analysis, and other information for system health initiatives such as maintenance as well as provision of new HW devices and other related actions. It also measures backbone pipe sizes and current utilization to govern use.

The Slingroute module itself also offers a targeted routing mechanism to not just a PFS but also to one of various folders on that PFS. These folders can be used to run parallel batch file processes, as well as to apply different quality of service (QoS) to each folder. For example, some folders can be read more frequently than others such as in the case of financial information conveyance or trade order or trade confirmation passing. These shorter and more frequent intervals ensure that the Slingshot mechanism adds as minimal time delay as possible. Other folder QoS like large file transfer can be at longer intervals and called comparatively less frequently while still not impacting client performance expectations.

Slingroute forms the basis for targeting the sending of data via Data Beacon Pulser (DBP), Slinghop, and other related sling technologies.

Slingroute leverages slingshot's reliability to send data as fast as possible to exact target destination in a highly controlled and predictable manner. Being able to place files in exact folder in specific location for the best sling node (SLN) and backbone exchange server (SRV_BBX) to fetch and use data is a vast improvement over IP routing and transport, as well as over a basic Slingshot mechanism without Slingrouting.

Addressable, automated routing of sling transfers of files to PFS folders are determinable with exact time for deliver to be predicted. Slingroute QoS to a specific folder can also specify a number of parallel streams to send data which has a direct impact on delivery time of last byte after receipt of first byte. The folder itself can determine the regularity of processing of batches of received files for control over QoS or various types of data and can therefore be differential based on best use.

Slingroute integrates easily into the sling ecosystem. It enhances Slingshot, Slinghop, Data Beacon Pulser (DBP) and other sling related technologies. It further enhances the integration of Sling technology into a GVN.

Disclosed systems and methods offer the ability to route data with options using Slingshot, Slinghop, DBP, and other related sling technologies to send to the most appropriate PFS in the target region and also with built-in choice of quality of service (QoS) based on which folder on target PFS that the file is written to. Granularity of a Tick governs the sequencing of the file reads in the remote regions when the folder is accessed by sling nodes (SLN). Higher priority items can be processed more frequently in batches with higher levels of CPU, RAM, and other resources committed to the fastest handling as possible by the SLN. Lower priority items can be accessed less frequently, committing fewer resources for those read batches. Slingroute offers sending addressing by Region ID, IP address, PFS+Folder Name, Unique folder name, other label and/or other addressing systems. The receiving devices can also know the source region of the incoming files based on the folder that the file was written into. This can also be a factor in determining sequencing, priorities, and other aspects of sling transfers. This information available to both the sender and the receiving devices can also be a factor in making sling transfer as efficient as possible. Sling route also presents the ability to have high availability for sling transfers which are transparent to both senders and receivers. More devices can be added to the pool at either end and to fulfill their roles, and those devices which are broken, need maintenance, overloaded, or otherwise not available can be bypassed without interruption to the flow of data.

In addition, it will be understood that the examples provided below are exemplary, and that it is contemplated that there are other systems, methods, and media that are within the scope of the disclosed subject matter.

<FIG> illustrates a global virtual network (GVN). This figure demonstrates prior art of a GVN integrated as an over-the-top (OTT) layer over the internet. Another example embodiment illustrated is a slingshot cluster in the middle <NUM>-RGN-ALL via <NUM>-CPT280 and <NUM>-CPT282. <FIG> illustrates a global virtual network (GVN) or similar globally distributed network using hub and spoke topology with octagon routing on the backbone, with egress/ingress points (EIP) noted. The octagon shape is for illustrative purposes only - the physical construct can be any shape topology.

<FIG> shows the network topology of a GVN in two different regions <NUM>-RGN-A and <NUM>-RGN-B and how the regions are connected via paths <NUM>-P0A and <NUM>-P0B through global connectivity <NUM>-RGN-ALL. In addition, <FIG> demonstrates the hub & spoke connections in each of the two regions. The multiple egress-ingress points (EIP) <NUM>-EIP400, <NUM>-EIP420, and <NUM>-EIP410, <NUM>-EIP430 in each region are added spokes to the hub and spoke model.

SRV_BBX <NUM>-<NUM> and SRV_BBX <NUM>-<NUM> are backbone exchange servers (SRV_BBX) and provide the global connectivity. A SRV_BBX may be placed as one or more load- balanced servers in a region serving as global links to other regions. Access point servers (SRV_AP) <NUM>-<NUM>, <NUM>-<NUM> and <NUM>-<NUM> in <NUM>-RGN-A connect to SRV_BBX <NUM>-<NUM>- via <NUM>-L302, <NUM>-L304, and <NUM>-L306, respectively. Access point servers (SRV_AP) <NUM>-<NUM>, <NUM>-<NUM> and <NUM>-<NUM> in <NUM>-RGN-B connect to SRV_BBX <NUM>-<NUM>- via <NUM>-L312, <NUM>-L314, and <NUM>-L316, respectively.

The central, control server (SRV_CNTRL) <NUM>-<NUM> serves all the devices within that region, and there may be one or more multiple master SRV_CNTRL servers. The central, control server SRV_CNTR <NUM>-<NUM> can connect to the backbone exchange server SRV_BBX <NUM>- <NUM> via <NUM>-L200. End-point devices (EPD) <NUM>-<NUM> through <NUM>-<NUM> will connect with one or more multiple SRV_AP servers through one or more multiple concurrent tunnels. For example, EPD <NUM>-<NUM> through <NUM>-<NUM> can connect to the region <NUM>-RGN-A via tunnels <NUM>-P100 through <NUM>-P110.

The central, control server (SRV_CNTRL) <NUM>-<NUM> serves all the devices within that region, and there may be one or more multiple master SRV_CNTRL servers. The central, control server SRV_CNTR <NUM>-<NUM> can connect to the backbone exchange server SRV_BBX <NUM>-<NUM> via <NUM>-L202. End-point devices (EPD) <NUM>-<NUM> through <NUM>-<NUM> will connect with one or more multiple SRV_AP servers through one or more multiple concurrent tunnels. For example, EPD <NUM>-<NUM> through <NUM>-<NUM> can connect to the region <NUM>-RGN-B via tunnels <NUM>-P120 through <NUM>-P130.

This figure further demonstrates multiple egress ingress points (EIP) <NUM>-EIP420, <NUM>- EIP400, <NUM>-EIP430, and <NUM>-EIP410 as added spokes to the hub and spoke model with paths to and from the open internet. This topology can offer EPD connections to an EIP in remote regions routed through the GVN. In the alternative, this topology also supports EPD connections to an EIP in the same region, to an EPD in the same region, or to an EPD in a remote region. These connections are securely optimized through the GVN. This also facilitates the reaching of an EPD from the open internet with traffic entering the EIP nearest to the source and being carried via the GVN realizing the benefits of the GVN's optimization.

In some embodiments, a host server, a host client, and a DNS server can connect to an egress ingress point via the internet. Example host servers include host servers <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM> that can connect to the internet <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM> via <NUM>-P-<NUM>, <NUM>-P-<NUM>, <NUM>-EIP-<NUM>, <NUM>-P432, respectively. Example host clients include host clients <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM> that can connect to the internet <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM> via <NUM>-P402, <NUM>-P416, <NUM>-EIP426, <NUM>-P436, respectively. Example DNS servers include SRV_DNS <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM> that can connect to the internet <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM> via <NUM>-P404, <NUM>-P414, <NUM>-EIP424, and <NUM>-P434.

RGN means Ring Global Node(s) or Regional Global Node(s). RGN_ALL means All Linked Global Nodes. "Managed by MRGN" means Manager of Regional Global Nodes or Mesh of Regional Global Nodes.

<FIG> illustrates a Secure Perimeter with GVN above and infrastructure layer below. There exists a Secure Perimeter <NUM>-<NUM> which is between the IP / Internet layer <NUM>-<NUM> and the BB / Backbone layer <NUM>-<NUM>. The Secure Perimeter <NUM>-<NUM> can function with firewall type operations to isolate the above layers from the layers below. Another built-in protection concerns the nature of the transport. Packets travel along path <NUM>-TR6AP, and files are written via RDMA to PFS devices via path <NUM>-TR6BP. Files cannot natively move at the IP layer, and packets cannot be transported via the BB layer.

<FIG> illustrates a GVN Topology with routing via internal hops of construct OTT. This example embodiment demonstrates multiple tunnels between devices within a global virtual network (GVN) across multiple regions. The EPD <NUM>-<NUM> is in one location <NUM> -M0. SRV_APs in region <NUM>-M2 are SRV_AP <NUM>-<NUM>, SRV_AP <NUM>-<NUM>, and SRV_AP <NUM>-<NUM>. SRV_APs in region <NUM>-M4 are SRV_AP <NUM>-<NUM>, SRV_AP <NUM>-<NUM>, and SRV_AP <NUM>-<NUM>. EPD <NUM>-<NUM> can be linked to SRV_APs <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM> via tunnels TUN <NUM>-T00, <NUM>-T02, <NUM>-T04, respectively. SRV_AP <NUM>-<NUM> can be linked to SRV_AP <NUM>-<NUM> via tunnel TUN <NUM>-T20. SRV_AP <NUM>-<NUM> can be linked to SRV_AP <NUM>-<NUM> via tunnel TUN <NUM>-T22. SRV_AP <NUM>-<NUM> can be linked to SRV_AP <NUM>-<NUM> via tunnel TUN <NUM>-T10. SRV_AP <NUM>-<NUM> can be linked to SRV_AP <NUM>-<NUM> via tunnel TUN <NUM>-T12. SRV_AP <NUM>-<NUM> can be linked to SRV_AP <NUM>-<NUM> via tunnel TUN <NUM>-T14. SRV_AP <NUM>-<NUM> can be linked to SRV_AP <NUM>-<NUM> via tunnel TUN <NUM>-T30. SRV_AP <NUM>-<NUM> can be linked to SRV_AP <NUM>-<NUM> via tunnel TUN <NUM>-T32. LAN <NUM>-<NUM> can connect to EPD <NUM>-<NUM> via <NUM>-CP000. The SRV AP <NUM>-<NUM> can connect to EIP remote <NUM>-<NUM> via <NUM>-CP510. EIP remote <NUM>-<NUM> can connect to the internet <NUM>-<NUM> via <NUM>-CP010. The SRV_AP <NUM>-<NUM> can connect to EIP remote <NUM>-<NUM> via <NUM>-CP512. EIP remote <NUM>-<NUM> can connect to the internet <NUM>-<NUM> via <NUM>-CP012. The SRV_AP <NUM>-<NUM> can connect to EIP remote <NUM>-<NUM> via <NUM>-CP514. EIP remote <NUM>-<NUM> can connect to the internet <NUM>-<NUM> via <NUM>-CP014.

There is a need to mitigate the risk of looping, wrong geographic destination routing, ASR remote redirect backtrack, broken links between SRV_APs, regions, and other problems. This is managed by routing and other techniques both on the EPD and on other devices within the GVN.

<FIG> illustrates prior art Slinghop with composition of file as clump of packets. This figure describes a "carrier" file which is sent via slingshot consisting of a payload of packets in the Body Data <NUM>-<NUM>. This example embodiment describes a file of data organized in three defined sections: Header Information <NUM>-<NUM>, Payload <NUM>-<NUM> containing Body Data, and a Footer <NUM>-<NUM>. This file could be stored in RAM, memory, saved to disk, or otherwise stored in another form of memory or storage.

Header can contain information about host origin, host destination, timestamp, and other information. Security information can be stored in fields in both the header and the footer section. This security information may hold references to keys to use for decryption, as well as other information.

Payload (Body Data) may be encrypted in whole or in part, or sent unencrypted. Payload checksum in the footer is used to validate the integrity of the body data. EOF notation in the Footer will indicate that the file has arrived, is complete and ready to be validated / verified for accuracy and then ultimately used.

This figure illustrates various small packets such as Packets <NUM>-A, <NUM>-C, <NUM>-D, or <NUM>-E, or larger packets such as Packet <NUM>-B. It also illustrates the inclusion of a data file <NUM>-F. These are combined when the file is created by the origin sling node (SLN) and are separated into separate packets when the file is accessed and utilized by the SLN at the other end of the Slingshot path. The number and size of contents in the payload (body data) <NUM>-<NUM> of this example embodiment are for illustrative purposes only and in practical use, the number, size, configuration of elements within the payload are different and varied. Total file size <NUM>-<NUM> can be the sum of header information size, payload size, and footer size.

<FIG> illustrates layers either over the top (OTT) or under the internet (UTI). This figure presents the example embodiments of various layers of the GVN, starting at the Base network connectivity <NUM>-<NUM> of the Internet <NUM>-TOP80. The Global virtual network (GVN) is over-the-top of the internet (OTT) and in this scope, is a first-degree OTT or OTT<NUM>. An example of a second-degree OTT or OTT<NUM> <NUM>-TOP84 is the Multi-perimeter firewall mechanism (MPFWM <NUM>-<NUM>) The basic slingshot mechanism in this scope is a first degree under-the-internet (UTI) or UTI<NUM> and the Slingrouting is a second degree UTI or UTI<NUM>. <FIG> indicates the level where Slingshot BB5-<NUM> fits into a topological hierarchy as UTI<NUM> <NUM>-UNDER86. OTT<NUM> indicates first degree over-the-top of the internet. OTT<NUM> indicates second degree over-the-top of the internet, meaning that it is over-the-top of an OTT<NUM> element. UTI<NUM> indicates first degree under-the-internet layer. UTI<NUM> indicates second degree under-the-internet layer which is below the UTI<NUM> element. OTT and UTI are used for descriptive purposes only to indicate the layering of relationships and interactions. At the physical layer, all types of protocols may exist at the same level or at different levels than illustrated herein. Global virtual network (GVN <NUM>-<NUM>) is at layer OTT<NUM> <NUM>-TOP82 which is built upon the basic plumbing of the Base Internet <NUM>-TOP80 on top of ISP network connectivity <NUM>-<NUM>. The Sling routing BB <NUM>-<NUM> mechanism is a second degree UTI at layer OTT<NUM> <NUM>-UNDER88. It utilizes the UTI<NUM> technology of Slingshot BB <NUM>-<NUM>. The product of its functionality can be integrated into the flow of GVN <NUM>-<NUM> which is at layer OTT<NUM> <NUM>-TOP82 or integrated as a segment in an internet path at level Base Internet <NUM>-TOP80. An example of second degree OTT of MPFWM <NUM>-<NUM> at layer OTT<NUM> <NUM>-TOP84 is noted for illustrative purposes only. In live implementations, it may or may not be integrated into the traffic flow.

<FIG> illustrates prior art Slingshot with two or more slingshot nodes working in unison. This figure demonstrates the operation of two independent slingshot mechanisms (see <CIT> or <CIT>) juxtaposed with each other and overlaid into an integrated relationship.

Traffic flows from the first region's global virtual network (GVN) <NUM>-<NUM> to the second region GVN <NUM>-<NUM> following this pathway: to the access point server (SRV_AP) <NUM>-<NUM> via <NUM>-P322 and onto backbone exchange server (SRV_BBX) <NUM>-<NUM>. At this point, the slingshot mechanism on SRV_BBX <NUM>-<NUM> via its Write Queue <NUM>-WQ502 function converts the packetized traffic into a combined carrier file and directly writes this carrier file via path <NUM>-W606 to the parallel file system (PFS) storage node <NUM>-<NUM>. The Read Queue <NUM>-RQ-<NUM> function of SRV_BBX <NUM>-<NUM> retrieves the carrier file from PFS <NUM>-<NUM> via <NUM>-R606 and then it separates the carrier file back into individual packets which are sent to SRV_AP <NUM>-<NUM> via path <NUM>-P506 and then onto the GVN <NUM>-<NUM> via <NUM>-P326. GVN is provided as an example and in real-world practical use, slingshot could be integrated into another network type.

Traffic flows from GVN <NUM>-<NUM> to GVN <NUM>-<NUM> following this pathway: to the access point server (SRV_AP) <NUM>-<NUM> via <NUM>-P326 and onto backbone exchange server (SRV_BBX) <NUM>-<NUM>. At this point, the slingshot mechanism on SRV_BBX <NUM>-<NUM> via its Write Queue <NUM>-WQ506 function converts the packetized traffic into a combined carrier file and directly writes this file via path <NUM>-W602 to the parallel file system (PFS) storage node <NUM>-<NUM>. The Read Queue <NUM>-RQ-<NUM> function of SRV_BBX <NUM>-<NUM> retrieves the carrier file from PFS <NUM>-<NUM> via <NUM>-R602 and then it separates the carrier file back into individual packets which are sent to SRV_AP <NUM>-<NUM> via path <NUM>-P502 and then on to the GVN <NUM>-<NUM> via <NUM>-P322.

Each one-way communication path is powered by Slingshot as defined in US <NUM>/<NUM>,<NUM> noted above. Together, these two nodes and their corresponding communication paths work in unison to form the basis of the underlying Slinghop technology.

<FIG> illustrates prior art Slingshot with End Points Pairs (EPP) Topology overlaid on map of northern hemisphere. This figure demonstrates the geographic placement of a few global nodes of a GVN, and example connectivity paths. For illustrative purposes, the lines are drawn as straight lines between points. Due to political / administrative boundaries, cities limits, zoning, geographic features such as bodies of water, various elevation changes, and other reasons, the actual routes of pipes are rarely ever straight or direct. However, the additional distance caused by path deviations from the potentially most direct route do not add enough distance to have a significantly adverse effect of added latency. It is assumed that the lines follow the most optimal path possible, and enhancements herein focus on efficiency of utilization of these lines. For illustrative purposes, segments can be described as city or location pairs and for Slinghop purposes, the origin end-point of the Slinghop is represented by an IP Address or hostname or other label of a server or gateway device there, with segment transiting over the Slinghop segment to IP address or hostname or other label of the server or gateway device at the target end-point city / location. Transit from one location to the other is as simple as from origin IP address to target IP address and for the return path the IP addresses are in reciprocal order. This single Slinghop segment replaces many other IP segments over the internet and is optimized by Slingshot.

PFS naming can be based on last octet or last <NUM> octets of an IP address or other such hostname or other label naming scheme. PFS naming can also include city code, region, IP Address, noted world nodes, and more factors. IP address pairs denote bridgeheads at either end of a segment. For example, from <NUM>. <NUM> to <NUM>. <NUM> means that Slingshot will write to PFS <NUM>-<NUM>, or in other terms, and traffic from New York City NYC <NUM>-<NUM> will be directly written to a PFS <NUM>-<NUM> in London LDN <NUM>-<NUM>. And for return traffic, from <NUM>. <NUM> to <NUM>. <NUM> means that Slingshot will write to PFS <NUM>-<NUM>, or in other terms, and traffic from London LDN <NUM>-<NUM> will be directly written to PFS <NUM>-<NUM> in New York NYC <NUM>-<NUM>.

Like airline routes for roundtrips, the combination of two one-way segments constitute a Slinghop transparent roundtrip integration nested into an existing IP pathway. And to further this analogy, sling-routed traffic can be one way and or to various routes concurrently.

In the event of failure of one link such as <NUM>-P1226 from London LDN <NUM>-<NUM> to Tokyo TOK <NUM>-<NUM>, Slingroute can either save data to HKG <NUM>-<NUM> and then save this data to TOK <NUM>-<NUM> or it can relay through HKG <NUM>-<NUM> for save to TOK <NUM>-<NUM>. Other such redirects and re-routes can be utilized by Slingroute to get data to destination if the most direct path is compromised or otherwise unavailable.

Various paths or links (e.g., <NUM>-P600, <NUM>-P612, <NUM>-P0026, <NUM>-P0028, <NUM>-P0012, <NUM>-P1226, <NUM>- P1228, <NUM>-P20) can be made between cities, or between a city and a PFS (e.g., PFS <NUM>-<NUM>, PFS <NUM>-<NUM>, PFS <NUM>-<NUM>, PFS <NUM>-<NUM>).

<FIG> illustrates Sling-Routing with Ring of Global Nodes. This figure demonstrates the Slinghop internals and operations with respect to topological structure. This figure is not to scale nor is the octagonal shape of any significance other than being able to organize information for human visual understanding. It demonstrates how backbone exchange servers (SRV_BBX) and sling nodes (SLN) <NUM>-<NUM> through <NUM>-<NUM> can access and write to various PFS devices such as PFS <NUM>-<NUM> through PFS <NUM>-<NUM>. They are all connected via an internal backbone of various joined segments <NUM>-P502 through <NUM>-P516.

As an example, it shows how the Slinghop can integrate with a GVN and some of its devices such as an access point server (SRV_AP) <NUM>-<NUM>, an end-point device (EPD) <NUM>, and a central control server (SRV_CNTRL) <NUM>. The circles with an E represent an egress-ingress point (EIP) to an EPD. SRV_BBX / SLN <NUM>-<NUM> can link to SRV_AP <NUM>-<NUM> via <NUM>-P302. SRV_AP can link to E via <NUM>-P102 and link to C via <NUM>-P202. The circles with a C represent an EIP to an SRV_CNTRL. Similar configurations can be available for other access point servers SRV_AP <NUM>-<NUM> through <NUM>-<NUM>, other backbone exchange servers and sling nodes SRV_BBX / SLN <NUM>-<NUM> through <NUM>-<NUM>, and other paths or links <NUM>-P102 through <NUM>-P1 <NUM>, <NUM>- P202 through <NUM>-P216.

The octagonal shape is not of material significance and is presented for illustrative purposes only. The actual shape may or may not be in a ring shape, or will take on other shape(s).

<FIG> illustrates Sling-Routing with Targeted Write to PFS to route traffic. Reference numerals in <FIG> that start with "<NUM>-" are numbered the same way in <FIG> for similar or same elements, except that "<NUM>-" has been replaced with "<NUM>-" in <FIG> is based on <FIG> with some exceptions. Differences between these example embodiments are that most of the bridgehead node points are faded. This is to highlight interaction between two bridgehead node points denoting Slinghop connectivity from Region <NUM><NUM>-ZN02 to Region <NUM><NUM>-ZN10 via SRV_BBX / SLN <NUM>-<NUM> to write via RDMA directly to PFS <NUM>-<NUM> with SLN / SRV_BBX <NUM>-<NUM> reading the carrier file and using it in Region <NUM><NUM>-ZN10. Reciprocal traffic in the other direction from Region <NUM><NUM>-ZN10 to Region <NUM><NUM>-ZN02 is written via RDMA by SRV_BBX / SLN <NUM>-<NUM> to PFS <NUM>-<NUM>. The carrier file is read by SRV_BBX / SLN <NUM>-<NUM> to be used there. These bridgeheads are bolded to highlight their place and focus. IP addresses are noted for illustrative purposes X. <NUM> at <NUM>-<NUM> and X. <NUM> at <NUM>-<NUM> as either end. Slinghop is therefore from Region <NUM><NUM>-ZN02 to Region <NUM><NUM>-ZN10 by IP order of X. <NUM> to X. <NUM>, and back from Region <NUM><NUM>-ZN10 to Region <NUM><NUM>-ZN02 via IP order of X. <NUM> to X.

In practical use, all connected nodes can concurrently connect with PFS devices in all other regions and locations. This figure focuses on the example embodiment of one two-way Slingroute.

<FIG> illustrates Ring of PFS devices with multiple SLN per location. This example embodiment is a continuation of <FIG> and it describes the flow between a backbone exchange server (SRV_BBX) such as <NUM>-<NUM>, <NUM>-<NUM> in Region B <NUM>-<NUM> or <NUM>-<NUM>, <NUM>-<NUM> in Region E <NUM>-<NUM>, sling nodes (SLN) <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM> in Region B <NUM>-<NUM> or <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM> in Region E <NUM>-<NUM>, and the physical ring linking regions to each other via InfiniBand or equivalent or other fast backbone communication protocol via ring <NUM>-P520 through <NUM>-P534. Parallel file system devices (PFS) where remote RDMA file writes are committed are also accessible via the global communications ring or another shaped topology.

The key example embodiments illustrated herein are that in each region there are multiple SRV_BBX, SLN, and PFS devices. In each region, two or more SRV_BBX servers offer high availability and failover. Flexible topology by device role also allows for rapid rollout and scalability. Each SRV_BBX can access one or more SLN, and each SLN is connected to all PFS devices (e.g., PFS <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>) in that region as well as other regions. <FIG> shows other regions including Region A <NUM>-<NUM>, Region C <NUM>-<NUM>, Region D <NUM>-<NUM>, Region F <NUM>-<NUM>, Region G <NUM>-<NUM>, and Region H <NUM>-<NUM>. Paths or links between a region and a SRV_BBX are shown using <NUM>-P520, <NUM>-P522, <NUM>-P580, and <NUM>-P582. Paths or links between an SRV_BBX and an SLN are shown using <NUM>-P820, <NUM>-P822, <NUM>-P824, <NUM>-P830, <NUM>-P832, <NUM>-P834, <NUM>-P880, <NUM>-P882, <NUM>-P884, <NUM>-P890, <NUM>-P892, and <NUM>-P894. Paths or links between an SRV_BBX and the ring are shown using <NUM>-P530, <NUM>-P532, <NUM>-P590, and <NUM>-P592. Paths or links between an SLN and the ring are shown using <NUM>-P836, <NUM>-P322, <NUM>-P838, <NUM>-P896, <NUM>-P882, and <NUM>-P898. Paths or links between the ring and a PFS are shown using <NUM>-P620, <NUM>-P622, <NUM>-P624, <NUM>-P680, <NUM>-P682, and <NUM>-P684. A path or link between Region A <NUM>-<NUM> and the ring is shown as <NUM>-P320.

This construct is designed with failover and high availability in mind as well as offering multiple Slingroute options for traffic to take. PFS and SLN devices are reliable through high availability.

<FIG> illustrates multi-folder access by multiple sling nodes (SLN). This example embodiment describes how multiple sling nodes (SLN) can access different folders on the PFS <NUM>-<NUM>. It illustrates SLN <NUM>-<NUM> and <NUM>-<NUM> in Region A SLR-A <NUM>-<NUM> being able to write directly to PFS <NUM>-<NUM> in another region, Region C. There are also SLN <NUM>-<NUM> and <NUM>- <NUM> in Region B <NUM>-<NUM> which can also write to PFS <NUM>-<NUM> in Region C. In Region C, there are also SLN <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, and <NUM>-<NUM> which monitor and can read and otherwise manage files which arrive there.

One example configuration is that each SLN in the target Region C can be assigned certain folders on PFS <NUM>-<NUM>. For example, Folder <NUM>-F610 is managed by the read queue process of <NUM>-RQ610 and once files have been read and used, the Post-Process <NUM>-WQ610 can mark those files in folder <NUM>-F610 as read. Similarly, read queue Process <NUM>-RQ620 and Post-Process <NUM>-WQ620 focus on folder <NUM>-F620. This is to permit different priority and handling for contents of each folder. For example, folder <NUM>-F610 might be set with a very short time interval between batch processing of received files to offer very high performance and the shortest possible processing time for files through the slingshot mechanism. Data written to folder <NUM>-F620 is accessed at a longer time interval between batch processing of received files and therefore has a different quality of service (QoS) specification. So Sling routing can differentiate and choose desired QoS based on the folder written to with the origin SLN such as <NUM>-<NUM> knowing that the target SLN <NUM>-<NUM> will process folders at various QoS rates.

Another example embodiment illustrated herein is for different sling nodes (SLN) to be able to access other folders on the same PFS <NUM>-<NUM>. This can be for load balancing, QoS reasons, high availability, different purpose of utilization, or other reasons.

Another example embodiment illustrated herein is that traffic from other regions is written to other folders such as SLN <NUM>-<NUM> writing to Folder <NUM>-<NUM> which is accessed by SLN <NUM>-<NUM>'s read queue Process <NUM>-RQ680 and read files marked by Post-Process <NUM>- WQ680. Folders can be labeled with a "from HERE" or "from THERE" label to note other otherwise classify source of sling traffic.

Other folders, including folders <NUM><NUM>-F660 through <NUM>-F690 can be configured similar to, or different from folder <NUM>-F610 or <NUM>-F620. These other folders can also include SRV BBX Processes (e.g., <NUM><NUM>-RQ630, <NUM><NUM>-RQ640, <NUM>-RQ660, <NUM>-RQ670, <NUM>-RQ680, <NUM>- RQ690) and SRV_BBX Post-Processes (e.g., <NUM>-WQ630, <NUM>-WQ640, <NUM>-WQ660, <NUM>- WQ670, <NUM>-WQ680, <NUM>-WQ690). Paths between PFS <NUM>-<NUM> and various SRV_BBX Processes can include <NUM>-RQP630, <NUM>-RQP640, <NUM>-RQP660, <NUM><NUM>-RQP670, <NUM>-RQP680, and <NUM>-RQP690. Paths between PFS <NUM><NUM>-<NUM> and various SRV_BBX Post-Processes can include <NUM>-WQP630, <NUM>-WQP640, <NUM>-WQP660, <NUM>-WQP670, <NUM>-WQP680, and <NUM>-WQP690.

SLN <NUM>-<NUM> can include write process <NUM>-WQ800. SLN <NUM>-<NUM> can link to SLR A <NUM>-<NUM> via <NUM>-Q800. SLN <NUM>-<NUM> can include write process <NUM>-WQ802. SLN <NUM>-<NUM> can link to SLR A <NUM>-<NUM> via <NUM>-Q802. SLN <NUM>-<NUM> can include write process <NUM>-WQ810. SLN <NUM>-<NUM> can link to SLR B <NUM>-<NUM> via <NUM>-Q810. SLN <NUM>-<NUM> can include write process <NUM>- WQ812. SLN <NUM>-<NUM> can link to SLR B <NUM>-<NUM> via <NUM>-Q812. SLR A <NUM>-<NUM> can link to various folders via <NUM>-Q610 through <NUM>-Q640. SLR B <NUM>-<NUM> can link to various folders via <NUM>-Q660 through <NUM>-Q690.

The specific number of folders and corresponding read queues Processes and Post- Process managers will vary in real-world deployment. SLN managers can dynamically add, modify, or otherwise manage the folders and their QoS rating. Each SLN can also write to and read from multiple PFS devices.

<FIG> illustrates various Sling Modules for integration and collaboration. This example embodiment describes the relationships between slingshot <NUM>-<NUM> and its technologies which it utilizes or otherwise interacts with such as granularity of a tick <NUM>-<NUM> and a global virtual network (GVN) and its associated technologies <NUM>-<NUM>. Granularity of a tick <NUM>-<NUM> and Slingshot <NUM>-<NUM> govern the QoS and timing of sling transfers. Sling routing <NUM>-<NUM> is at the core and is built upon slingshot <NUM>-<NUM>. It also serves as a basis of sling hop <NUM>- <NUM> and beacon pulser <NUM>-<NUM>.

This figure also maps the interrelationships between them by using various paths or links, including <NUM>-P302, <NUM>-P210, <NUM>-P200, <NUM>-P300, <NUM>-P100, <NUM>-P320, <NUM>-P322, <NUM>-R600, and <NUM>-R602.

<FIG> illustrates SRV_BBX topology with options to multiple sling nodes (SLN) and associated PFS devices. This example embodiment describes the relationship between backbone exchange servers (SRV_BBX) and sling nodes (SLN) and parallel file systems (PFS) devices and their interrelationships, illustrating elements for high availability, load balancing and failover.

This figure describes the Slingroute options between Region A <NUM>-<NUM> and Region B <NUM>- <NUM>. It further illustrates two SRV_BBX <NUM>-<NUM> and <NUM>-<NUM> in Region A <NUM>-<NUM> and two SRV_BBX <NUM>-<NUM> and <NUM>-<NUM> in Region B <NUM>-<NUM>. Each SRV_BBX can read from one or more SLN <NUM>-<NUM>, <NUM>-<NUM>, and <NUM>-<NUM> in its region. In this example, three SLN devices are illustrated but the number of SLN, SRV_BBX, and PFS devices in use will vary based on demand, capacity to meet that demand, failover, and other considerations.

Each SLN <NUM>-<NUM>, <NUM>-<NUM>, and <NUM>-<NUM> in Region A <NUM>-<NUM> can write to PFS devices <NUM>-<NUM>, <NUM>-<NUM>, and/or <NUM>-<NUM> in Region B <NUM>-<NUM> for reading by SLN <NUM>-<NUM>, <NUM>-<NUM>, and/or <NUM>-<NUM> via paths <NUM>-PN60, <NUM>-PN70, and <NUM>-PN80. Similarly, an SLN in Region B can write to PFS devices <NUM>-<NUM>, <NUM>-<NUM>, and/or <NUM>-<NUM> in Region A <NUM>-<NUM>. Junction points in this diagram <NUM>-N10, <NUM>-N20, <NUM>-N30, <NUM>-N60, <NUM>-N70, and <NUM> -N80 are for illustrative purposes. They do not necessarily represent a specific device but could be a switch or other aspect of network path for sling traffic to be sling-routed via.

Paths or links between various elements of <FIG> include: <NUM>-P510, <NUM>-P530, <NUM>- P512, <NUM>-P532, <NUM>-P514, <NUM>-P534, <NUM>-P8516, <NUM>-P536, <NUM>-P810, <NUM>-P812, <NUM>-P814, <NUM>-P820, <NUM>-P822, <NUM>-P824, <NUM>-P830, <NUM>-P832, <NUM>-P834, <NUM>-P610, <NUM>-P620, <NUM>-P630, <NUM>-P622, <NUM>-P614, <NUM>-P624, <NUM>-P634, <NUM>-P612, <NUM>-P632, <NUM>-PN10, <NUM>-PN20, <NUM>-PN30, <NUM>-P660, <NUM>-P670, <NUM>-P674, <NUM>-P660, <NUM>-P662, <NUM>-P664, <NUM>-P672, <NUM>-P680, <NUM>-P682, <NUM>-P684, <NUM>-P680, <NUM>-P862, <NUM>-P864, <NUM>-P870, <NUM>-P872, <NUM>-P874, <NUM>-P880, <NUM>-P882, <NUM>-P884, <NUM>-P562, <NUM>- P582, <NUM>-P564, <NUM>-P584, <NUM>-P566, <NUM>-P586, <NUM>-P560, and <NUM>-P580.

This figure is to illustrate the flexibility of Slingrouting highlighting its various aspects.

<FIG> illustrates algorithm logic for evaluating best route type for traffic to take. Both ends of a slingshot mechanism add a certain amount of resistance in the form of needing computing resources such as processing, RAM, or other which injects a certain amount of time delay into a network path. This resistance and added time is illustrated by <NUM>-<NUM> and <NUM>-<NUM>. However, slingshot's efficiency over a long distance reduces the data transit time each way by a certain amount when compared to other long-haul network protocol transit such as comparing Slingshot to IP over Ethernet on the Internet. Therefore, a comparison <NUM>-<NUM> can be made end-to-end to evaluate if the gain over the long haul <NUM>-<NUM> using slingshot can offset the delay due to resistance at <NUM>-<NUM> and <NUM>-<NUM>. When the distance is great enough that the gain in <NUM>-<NUM> is more than the friction delay caused by <NUM>-<NUM> and <NUM>-<NUM>, then Slingshot and sling-routed traffic is the most optimal path for traffic to take. This figure can be a basis for evaluation of best traffic path in <FIG>. For example, <NUM>-<NUM> can describe the steps SRV_AP <NUM>-<NUM> to SRV_BBX <NUM>-<NUM> to SLN <NUM>-<NUM>, and <NUM>-<NUM> can describe the steps SRV_AP <NUM>-<NUM> to SRV_BBX <NUM>-<NUM> to SLN <NUM>-<NUM>.

The slingshot one way traffic <NUM>-SL508 can describe the RDMA write <NUM>-WQ502 via path <NUM>-W606 to PFS <NUM>-<NUM> to be read by SLN <NUM>-<NUM> Read Queue <NUM>-RQ506 via path <NUM>- R606. Slingshot one-way traffic <NUM>-SL518 can describe the RDMA write <NUM>-WQ506 via path W602 to PFS <NUM> to be read by SLN <NUM>-<NUM> Read Queue <NUM>-RQ502 via path <NUM>-R602.

<FIG> illustrates Slingshot / Slinghop as UTI alternative to either internet path <NUM>- P220 to <NUM>-P236 or TUN OTT <NUM>-<NUM> internet. This figure compares three traffic path types: one over the open internet via path <NUM>-P220 to <NUM>-P236, a second via a tunnel TUN <NUM>-<NUM>, and a third via a reciprocal Slinghop <NUM>-SL518 and back via <NUM>-SL508. The tunnel TUN <NUM>-<NUM> is over-the-top (OTT) of the internet, and Slinghop utilizes reciprocal Slingshot mechanisms over fiber back bone or equivalent high speed network which can support slingshot.

Algorithmic analysis can be applied to choose which transport type over which path is most optimal for the traffic to take considering latency, bandwidth, and other factors effecting overall efficiency for complete transfer of data from one region <NUM>-<NUM> to another <NUM>-<NUM>. The label Internet is applied at <NUM>-<NUM> and <NUM>-<NUM> for example only, as these end points via egress-ingress points <NUM>-<NUM> and <NUM>-<NUM> can link to intranets, LANs, and various other network fabrics. Paths or links between various elements can include <NUM>-P010, <NUM>-P012, <NUM>- P500, <NUM>-P510, <NUM>-P508, <NUM>-P518.

The lower portion of this figure (below SRV_BBX <NUM>-<NUM> and SRV_BBX <NUM>-<NUM>) operates in the same manner as the slingshot mechanism described in <FIG> herein. As components of a global virtual network (GVN), these path choices can be evaluated based on current network conditions, data type, QoS requirements, load, and other factors.

<FIG> illustrates Slingshot Manager and modules collaborating across various devices. This figure describes the collaboration between devices such as back bone exchange server (SRV_BBX) <NUM>-<NUM>, central control server (SRV_CNTRL) <NUM>-<NUM>, sling nodes (SLN) <NUM>-<NUM>, and parallel file systems (PFS) <NUM>-<NUM>, <NUM>-<NUM>. Slingrouting offers dynamic, realtime routing options for slingshot traffic to take based on target region, QoS, long-haul line state, and other factors.

To achieve optimal performance in real-time, devices need to share information about their operations including load factors, health, and other data. Sling Manager <NUM>-<NUM> on the SLN-<NUM><NUM>-<NUM> determines which sling route to take. Sling Manager <NUM>-<NUM> interacts with Sling Routing <NUM>-<NUM> governing which PFS the Sender <NUM>-<NUM> writes to, and the QoS for that transfer determining which folder to write the file to. In this example embodiment, Sling Manager <NUM>-<NUM> uses Sender <NUM>-<NUM> to write the file by slingshot to the folder <NUM>-<NUM> on PFS <NUM>-<NUM> in remote region <NUM>-<NUM> via path <NUM>-P660.

The listener <NUM>-<NUM> on SLN-<NUM><NUM>-<NUM> reads files in the incoming folder <NUM>-<NUM> on PFS <NUM>-<NUM> in the local region for processing by Read Queue <NUM>-<NUM>. Slingshot manager <NUM>-<NUM> controls the operations of Write <NUM>-<NUM> and Read <NUM>-<NUM>, as well as receiving performance related data about their operations. The sling manager local analyzes sling related operations, coordinates with Sling Routing <NUM>-<NUM>. It also shares information with Sling Routing module <NUM>-<NUM> on SRV_BBX <NUM>-<NUM> and with the module Server Availability <NUM>-<NUM> on SRV_CNTRL <NUM>-<NUM>, as well as with Sling Monitor <NUM>-<NUM> on SRV_CNTRL <NUM>-<NUM>.

Information from various devices and modules are received by SRV_CNTRL <NUM>-<NUM> and analyzed to determine current Sling Availability <NUM>-<NUM>. This availability is then shared contextually with devices with respect to sling availability for them. This forms the basis of the list generation of sling routing options available to senders such as <NUM>-<NUM> generated by Sling Routing <NUM>-<NUM>. Sling Routing <NUM>-<NUM> can further provide determinate estimates of time-to-transfer based on current and historical conditions.

There are other possible collaborative activities between devices and other modules which those described may collaborate with. In addition, the Read Queue <NUM>-<NUM> and Write Queue <NUM>-<NUM> may be bypassed, and other elements described herein may be altered but Slingroute will still function.

The GVN Manager <NUM>-<NUM> manages the operations and information about operation of related devices in the GVN, including central control servers (SRV_CNTRL), backbone exchange servers (SRV_BBX), sling nodes (SLN), parallel file system storage devices (PFS), access point servers (SRV_AP), end point devices (EPD) and other devices of the GVN.

Sling Hop <NUM>-<NUM> is the integration of slingshot into an internet pathway. One IP at one end is the ingress egress points (EIP) and the IP at the other end is the EIP. These two EIPs powered by reciprocal slingshots constitute a Slinghop.

The GVN manager <NUM>-<NUM> on the SRV CNTRL manages the repository of information for various GVN devices, as well as managing the peer pair relationships for neutral API mechanism (NAPIM), and other tasks. It also executes algorithms on logged data to analyze current operations, short, medium, and long term operations to identify trends as well as to take a predictive role in managing systems operations.

GVN <NUM>-<NUM> represents the global virtual network (GVN) which the Slingroute may integrate into. GVN <NUM>-<NUM> can also be internet or other network type such as a private WAN, etc..

PFS Monitor <NUM>-<NUM> on SLN devices such as SLN-<NUM><NUM>-<NUM> reacts with the operating systems of the PFS devices to gather information on the storage state, resources consumption, and other pertinent information about the PFS. This operational information is shared with Sling Manager <NUM>-<NUM> by PFS Monitor <NUM>-<NUM> in order to then provide a summary of information to the Sling Availability module <NUM>-<NUM> on SRV_CNTRL <NUM>-<NUM>. The modules PFS O/S <NUM>-<NUM> and PFS O/S <NUM>-<NUM> on PFS <NUM>-<NUM> and PFS-<NUM> respectively are the operating system of the PFS devices. These are the underlying controllers which handle the physical subsystems for device management, as well as to combine and make information available about their operations to other devices.

Paths or links between various elements of <FIG> include <NUM>-P508, <NUM>-P10, <NUM>-P538, <NUM>-P588, <NUM>-P568, <NUM>-P108, <NUM>-P210, <NUM>-P288, <NUM>-P536, <NUM>-P558, <NUM>-P556, <NUM>-P802, <NUM>- P280, <NUM>-P866, <NUM>-P816, <NUM>-P860, <NUM>-P862, <NUM>-P830, <NUM>-P810, <NUM>-P812, <NUM>-P610, and <NUM>- P620.

<FIG> illustrates Sling Route with Availability Modules collaborating across various devices. This figure refers to sling route availability module in accordance with certain embodiments of the disclosed subject matter. The device types described herein are backbone exchange server (SRV_BBX) <NUM>-<NUM> and <NUM>-<NUM>, central control server (SRV_CNTRL) <NUM>-<NUM>, parallel file system storage (PFS) <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, and sling nodes (SLN) <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>.

This figure graphically demonstrates the list of PFS and SLN devices available to SRV_BBX and SLN devices in each region. The SRV_BBX can act as an aggregation point for information about Slinghops which can then be utilized for Slingrouting. The Sling availability module (central) <NUM>-<NUM> on SRV_CNTRL <NUM>-<NUM> receives and processes information from all devices and publishes availability information to Sling availability modules (local) <NUM>-<NUM> and <NUM>-<NUM>. Other elements on an SRV_BBX not described herein may include local database, storage, control node governing PFS and SLN devices in its region, and more.

Both current and historical information is evaluated to understand current availability. Trend analysis is both valuable for resource planning as well as predictive applications.

When a device fails or its state is changed for instance so that it can undergo maintenance, this information is shared, processed; its availability state is marked as not available; and it is subsequently removed from the availability list.

Types of information shared from PFS to SRV_BBX could include state of device, storage levels, usage, problems or other health issues, etc. From the SRV_BBX to the PFS, instructions could be given to purge old files, to perform updates or other maintenance, resolve health issues, to create new or modify existing folder structure, and more. From SLN to SRV_BBX information could be shared such as device state, usage, traffic levels, problems or heath issues, and more. From the SRV_BBX to SLN the current PFS device availability list, state of cross-regional links, software updates, resolve issue, adjust queue priority levels, publish sling routes and sling availability information, and more. One SRV_BBX is in Region A <NUM>-<NUM>, and the other SRV_BBX is in Region B <NUM>-<NUM>. The central server can be somewhere in the middle or in another location but it must be reachable by both devices. This figure is focused on server availability module information sharing.

The analysis on SRV_CNTRL <NUM>-<NUM> does holistic system-wide global analysis as well as drill-down granular device or group of device analysis. Traffic analysis is done to anticipate expected load factors and to meet this with sufficient resources, making real time adjustments and that information automatically propagating to related devices.

<FIG> illustrates Slingroute with Availability Reporting module collaborating across various devices. This figure refers to Slingroute availability reporting in accordance with certain embodiments of the disclosed subject matter. It focuses on various modules and component parts of the sling availability mechanism with specific focus on SRV_CNTRL <NUM>-<NUM> expanding upon SRV_CNTRL <NUM>-<NUM>. The devices described herein are central control server (SRV_CNTRL), backbone exchange server (SRV_BBX), and a host for a graphic user interface (Host-GUI) <NUM>-<NUM>, as well as an inference to a browser rendering the GUI content on a client device <NUM>-<NUM>. <FIG> is a more detailed expansion of <FIG>.

<FIG> describes information stored in databases such as Db <NUM>-<NUM> storing information about this specific device and its operations, and Db Repos. <NUM>-<NUM> which stores information about resources in list form such as list of sling nodes <NUM>-<NUM>, list of regions <NUM>-<NUM>, list of PFS devices <NUM>-<NUM>, list of folders on PFS device <NUM>-<NUM>, and other information.

The sling availability reporting module has a listener <NUM>-<NUM> which receives information from SRV_BBX devices such as <NUM>-<NUM> from its local sling availability module <NUM>-<NUM>. This information is shared with the sling availability module <NUM>-<NUM> on SRV_CNTRL <NUM>-<NUM>. It is also analyzed by Analyzer <NUM>-<NUM>. Data from various device data feeds via <NUM>-P502 as well as data from the repository database <NUM>-<NUM> are compared and analyzed by availability calculators <NUM>-<NUM>. The data aggregator <NUM>-<NUM> takes results and broadcasts them via Sling availability reporting broadcaster <NUM>-<NUM> to various SRV_BBX such as <NUM>-<NUM> via path <NUM>-P512 for use by the local sling availability module <NUM>-<NUM> there.

Slingroute list manager integration <NUM>-<NUM> describes the possibility for this list to be utilized by related devices, such as sling nodes (SLN), or others.

Paths or links between various elements of <FIG> include <NUM>-P110, <NUM>-P122, <NUM>-P222, <NUM>-P606, <NUM>-P608, <NUM>-P210, <NUM>-P212, <NUM>-P216, <NUM>-P218, <NUM>-P220, <NUM>-P226, <NUM>-P228, <NUM>-P224, <NUM>-<NUM>, <NUM>-P250, <NUM>-P258, <NUM>-P230, <NUM>-P236, <NUM>-P238, <NUM>-P252, <NUM>-P256, and <NUM>-P268.

The modules API <NUM>-<NUM> and API <NUM>-<NUM> refer to the neutral application programming interface module (NAPIM) for communication between the central control server (SRV_CNTRL <NUM>-<NUM>) and the host device where the GUI is running <NUM>-<NUM>. GUI Host <NUM>-<NUM> is a device such as a laptop computer, mobile phone, tablet, or other device which can connect to the GUI host device <NUM>-<NUM> to receive GUI content and render it into a browser on the client. Db <NUM>-<NUM> is the database which stores data relevant to device SRV_CNTRL <NUM>-<NUM>. The repository database <NUM>-<NUM> stores information about various devices which either send information to or receive information from SRV_CNTRL <NUM>-<NUM>. Repository of Resources <NUM>-<NUM> manages the various lists of SLN sling nodes <NUM>-<NUM>, of various regions where infrastructure is located <NUM>-<NUM>, of various storage devices in those regions <NUM>-<NUM>, as well as a list of target folders and their types on various PFS devices <NUM>- <NUM>, and other information.

<FIG> illustrates Sling Route with an algorithm to assess sling availability per state and utilization rate. This figure refers to an algorithm to assess sling route availability per state and utilization rate in accordance with certain embodiments of the disclosed subject matter. It begins at Start <NUM>-<NUM>.

The availability of PFS devices, sling nodes and other information is received via the storing of PFS state info <NUM>-<NUM> and SLN state info <NUM>-<NUM> into database DB <NUM>-<NUM>. Using PFS location <NUM>-<NUM> and Folder lister <NUM>-<NUM>, folder and location information is pulled from DB <NUM>-<NUM> and made available to PFS selector <NUM>-<NUM> via path <NUM>-P110. The rationale is that the SLN state info <NUM>-<NUM> is required so that not only is desired PFS <NUM>-<NUM> known and selected <NUM>-<NUM>, but that there are sufficient corresponding SLN devices to manage the read.

Once the PFS in target region is selected at <NUM>-<NUM>, its state and health is checked at <NUM>-<NUM> against the most current database entry generating list from <NUM>-<NUM>. If it is okay <NUM>-P130, the generated folder list from <NUM>-<NUM> is further checked to see if the target folder at desired QoS is available (<NUM>-<NUM>). If it is available (<NUM>-P500), then the direct write is executed to target folder on remote PFS <NUM>-<NUM>. The sling write is checked at step <NUM>-<NUM> and if successful <NUM>-P900, this ends a successful sling write <NUM>-<NUM>.

If there is a problem with target PFS <NUM>-P124, then an alternative PFS is chosen at step <NUM>-<NUM> to be evaluated. If an PFS is okay (<NUM>-P130) but the target folder is unavailable, an alternative PFS and folder is chosen <NUM>-<NUM> via path <NUM>-P134. A key point is that the current state of each device is automatically published to other devices so that the target selection is dynamic and in real time based on known information. If there is a lag during the write due to a changing condition, the unsuccessful write is caught at step <NUM>-<NUM> and via <NUM>-P144, an alternate PFS and target folder can be selected <NUM>-<NUM> for another try at a write.

Paths or links between various elements of <FIG> include <NUM>-P115, <NUM>-P200, <NUM>- P210, <NUM>-P220, <NUM>-P100, <NUM>-P120, and <NUM>-P140.

<FIG> illustrates Virtualization Abstraction of PFS folders for load balancing and failover. This example embodiment demonstrates a sling node (SLN) writing to a virtualized abstraction layer to a PFS folder type <NUM>-<NUM> which could be written to one of many PFS devices such as <NUM>-<NUM>, <NUM>-<NUM>, or <NUM>-<NUM> illustrated herein. The LB_PFS <NUM>-<NUM> demonstrates how a PFS target may be load balanced.

PFS <NUM>-<NUM> can include PFS O/S <NUM>-<NUM> and Folder (incoming) <NUM>-<NUM>. PFS <NUM>-<NUM> can include PFS O/S <NUM>-<NUM> and Folder (incoming) <NUM>-<NUM>. PFS <NUM>-<NUM> can include PFS O/S <NUM>-<NUM> and Folder (incoming) <NUM>-<NUM>. SLN <NUM>-<NUM> can slingshot write to a remote region (<NUM>-P800) such as virtual folder (incoming) <NUM>-<NUM>.
