iPOP2019 Showcase:“End-to-End Network Slicing
with Transport Network Coordinationand Edge Cloud Applications in 5G Era”

Introduction:
Industries will be undergoing significant and radical evolution, which will challenge their“digital transformation” to enable new services and revenue growth in the 5G networks thatprovide eMBB(enhanced Mobile BroadBand), URLLC(Ultra-Reliable and Low LatencyCommunications) and mMTC(Massive Machine Type Communications). Those 5G requirements
and specifications are designed as “cloud native”. Many technologies and solutions are
inherited from cloud computing and virtualization to realize new service use cases such as
MR(Mixed Reality), IoT (Internet of Things), Health care, V2X(Vehicle to everything) and so on.

iPOP2019 Showcase White Paper (Issue 2)“Network Slicing” is an important and mandatory feature to provide diverse services overTransport Networks (TNs). Yet, only instructions of requirements to the relevant TN is stipulated.
Operations and management requirements for TN to satisfy 5G service requirements remain
unstipulated.
We believe methods and standards for coordinated management between TN and 5G“Network Slicing” is the most important domain for the future 5G TN and services architectures.
“TN Slice” needs to be coordinated and managed according to each 5G application’s performancerequirement. How “TN Slice” should be mapped into the specific slice of NG RAN (Next Generation
Radio Access Network) and 5GC (5G Core) is the biggest issue and needs to be addressed torealize optimized 5G TN.
At iPOP2019 showcase, we focused on 5G’s “Network Slicing” requirements from Transport
Network(TN) view points and tried to demonstrate possible scenarios of coordination between 5GC
and operation and management of TN.

Showcase Test Bed Configuration:
Figure.1 shows the iPOP2019 Showcase testbed conceptual configuration.

Note: In this demonstration, 5GC and NGRAN is not included

Figure 1 Showcase Network Concept
Assuming 5GC and NG RAN are (virtually) available in this environment, showcase test beds
(implemented with four-layer-configurations) are:● Transport Network● Edge Clouds● Operations Automation & Orchestration● 5G V2C(Virtual to Cloud) Applications

On the top, we have implemented two types of 5G applications as examples:●●Contents Distribution ​Service (by NICT: National Institute of Information andCommunications)
Autonomous Driving Vehicle Service ​(by Keio University)

These 5G services are instantiated as Virtual Network Functions (VNF) in each Edge Cloud, andtrigger API GW to create “5GC Network Slice” and coordinated TN resources, which we call “TNSlice”, according to each service’s requirement.
To orchestrate and coordinate “5GC Network Slice” and “TN Slice” with each 5G services, we have
implemented the following softwares, whose operations are automated:●●3scale API GW software(Red Hat) running in OKD (Open Kubernetes
Distribution)/Openshift (Red Hat) : Providing the API infrastructure to manage APIs forinternal or external users brokerage/coordination services among multiple 3rd party
applications and 5G infrastructure.
Ansible TOWER (Red Hat) and​MSActivator (UBiqube) : Providing Operations
Automation, Zero Touch Provisioning and Orchestration for Edge Cloud and TN (TNSlices). Ansible tower and MSActivator configured Fujitsu Open ROADMs and Alaxala
Routers respectively for network slicing in data networks.

Please note that each software is Open Source based and each community is actively generating
up-to-date features enhancements.
● OpenMSA
https://www.openmsa.co/● Ansible Tower https://www.ansible.com/products/awx-project● 3scale
https://github.com/3scaleOpen and multi vendor devices can be automatically configured by IaC (Infrastructure as Code)with Open Source based software to maintain and/or scale operations for a massive number ofdevices, accelerating time to market.
TN infrastructure is configured by following technologies:● Reconfigurable Communication Processor(by Keio University and ALAXALA Networks Corporation)● L2, L1 and L0(Optical) multi-layer switches​(by OA Laboratory)● 100G OpenROADM​(by Fujitsu Limited)● Fast and precise localization of failures in optical network ​(by NTT)
Open and Disaggregated Transport technologies are proceeding to avoid vendor lock-in andreduce costly proprietary software development efforts. Open ROADM MSA (Multi-SourceAgreement) is one of the solutions for this requirement.
In the TN, we also implemented ​“Active Monitoring” ​with Network Test and Visibility solutions forapplication level communication quality management by Keysight Technologies.

1. Operations Automation and Orchestration (UBiqube and Red Hat)
We demonstrated Open API and zero touch provisioning. With authorized REST API from 3scale
API Gateway, Ansible tower and MSActivator configured TN Slices. In this automation,
coordination between 5GC “Network Slice” and “TN Slice” can be realized.

[Red Hat] ​In 5G digital world, APIs are key to agile integration and delivering Biz value. 3scale
API Management makes it easy to manage 3rd party APIs, share, secure, distribute, control, andmonetize 3rd party APIs on mobile infrastructure built for performance, customer control, and future
growth.
[UBiqube] ​In 5G, with the rise of IOT and AR/VR, SP(Service Provider) are keen to pushprocessing at the edge and deploy applications on demand. Networks must be dynamicallyorchestrated overtime. MSActivator orchestrates all the domains (SDN, VNF, PNF) for end to end5iPOP2019 Showcase White Paper (Issue 2)

automation. MSActivator can not only activate services but also perform day2 changemanagement.

Autonomic Resource Management for Service Function Chaining Platform (NICT)

NICT has developed a service function chaining (SFC) platform specified in IETF RFCs 7665 and8300, and designed an autonomic resource management system for the SFC platform. In thisshowcase, we demonstrate the network function (NF) migration mechanism to guarantee QoS ofVoD services while optimally utilizing resources.

Multi-access Edge Computing Service for Autonomous Driving Vehicle Control (KeioUniv., ALAXALA Networks, OA Lab)​Multi-access Edge Computing (MEC) provides various networking services. Computing server
resources are located near users, i.e., in edge servers. In this demonstration, a MEC cloud
constructed by computing servers and Reconfigurable Communication Processors (RCPs), which
provide both an IP/Optical transport function and a computing function, is presented. ALAXALA
Networks provides the RCP prototypes which support over 100 Gbps interfaces and edge server
functions.

Keio University provides the RCP simulators and the RCP Manager. The unique feature of thismanager is using a biological attractor selection method for determining the location of functions.
OA Laboratory provides the MEMS-based optical layer 1 switch, 10 Gbps layer-1 switch and small
embedded type layer-2 switch for constructing an optical layer2/3 service network which is used forproviding 5G transport and edge clouds network in this showcase. Fujitsu’s open disaggregated
ROADM is also used in the network.
A network-controlled Autonomous Driving Vehicle (ADV) with high mobility is one of theimportant applications of MEC. Cloud, edge, and local coordination are required. In thisdemonstration, Keio University provides an ADV-control system prototype, and OA Laboratory
provides Power over Ethernet (PoE) Hub system with camera as a sensor for ADV.
