Title: A method and apparatus for controlling the flow of variable-length packets through a multiport switch
Inventor: BAUMAN JAMES A
IPC: H04L12/56
Filed: 1999-04-29
Abstract: A method and apparatus for controlling the flow of variable-length packets to a multiport switch involve accessing forwarding information in a memory (214) based at least partially on layer 4 information from a packet and then forwarding (186) the packet only if the packet is within a bandwidth consumption limit that is specified in the forwarding information. In a preferred embodiment, a credit bucket algorithm is used to ensure that packet flows are within specified bandwidth consumption limits. The preferred method for implementing the credit bucket algorithm to control flows of packets involves first receiving a particular packet from a flow and then stripping the layer 2 header information from the packet. The layer 3 and layer 4 information from the packet is then used to look-up (170) flow-specific forwarding and flow control information in a memory that stores a linked list of table entries that includes the fields necessary to implement the credit bucket algorithm. The credit bucket algorithm is implemented in embedded devices within an application-specific integrated circuit, allowing the control of packet flows based on the application of the flow.

Patent CA-2338086-A1 (CA)
Title: Routing of internet calls
Inventor: RAINWATER JAMES S
IPC: H04Q3/00
Filed: 1999-07-20
Abstract: When a subscriber calls into its Internet Service Provider (ISP), a central office receiving the call is triggered to perform a Local Number Portability (LNP) query. This LNP query is sent to an Intelligent Traffic Routing and Control (INTRAC) unit resident on a Service Control Point (SCP) which determines whether the call is to an ISP. If the call is to an ISP, the INTRAC  unit polls a Remote Authentication Dial-In-User Service (RADIUS) server to determine whether resources are available. The RADIUS server tracks the resources of the ISP and of other ISPs and informs the SCP of the available resources. The SCP then inserts the Local Routing Number (LRN) of the preferred resource into a reply that is sent to the central office. If resources are not available, the call is terminated before signaling occurs with any switch associated with the ISP. On the other hand, when resources are available, the subscriber can be directed to the preferred resource for the subscriber. The subscriber, for instance, can be directed to an access server within the ISP that has excess capacity or can be directed to an access server that provides the best service for the subscriber, whereby subscribers can be directed to X2 type service if they have an X2 modem or to K56Flex type service if they have a K56Flex modem. As another example, if one ISP is at maximum capacity, the subscriber can be directed to a second back-up ISP.

Filed: 2001-08-16
Abstract: According to one aspect of the invention a light filter is provided which includes a first light filter layer and a first counteracting ring. The first light filter layer is of a filter material that transmits a selected transmission range within a wider range of wavelength of light, and reflects another selected reflection range of the wavelengths. The filter material has a refractory index, heating of the first light filter layer tending to cause an increase in refractory index with a corresponding increase in the transmission range in a first direction. The counteracting ring is circumferentially attached to the first light filter layer so that at least some of the light transmits through an aperture. Heating of the first counteracting ring causes enlargement of the first counteracting ring. The selected transmission range is thereby at least in part stabilized.

Title: Method and device for the strapping of stacks of printed products
Inventor: MULLER ERWIN
IPC: B65B27/08
Filed: 2001-08-30
Abstract: For the sequential strapping of stacks of printed products (3) with a strapping tape (27), the stacks are conveyed to a strapping position pressed together between two presser arms (8.1 and 8.2.) and there strapped in a pressed together condition, in that a loop of the strapping tape (27) positioned around the stack (3) is tightened, locked and cut-off from a supply roll. In doing so, the tape loop is applied in the zone of the face sides of the stack outside the presser arms (8.1 and 8.2.) and aligned to slot-shaped apertures (19.1, 19.2) in the presser arms (8.1 and 8.2.) in such a manner, that the strapping tape (27), when it is being tightened, is moved through the apertures (19.1, 19.2) and comes to lie directly on the face sides of the stack. The strapping illustrated is advantageous in particular to strap stacks (3), which have either been previously - or are being simultaneously enveloped with a an enveloping material (25), whereby the envelope is applied around the stack (3) and the presser arms (8.1 and 8.2.), and the strapping is applied outside of the envelope.

Abstract: Improved separations of xylose, mannose, galactose, arabinose, glucose, xylitol, arabitol, sorbitol, galactitol, or mannitol (and other monosaccharides and sugar alcohols) from other sugars and sugar alcohols may be achieved by chromatography over hydroxyl-form anion exchange surfaces prepared from anion exchange resins at relatively low hydroxyl concentrations. When a strong base anion exchange resin, such as a chloride-form strong base anion exchange resin, is conditioned with a low concentration of hydroxyl (for example, an NaOH solution with a concentration between 0.1 and 1000 nM, most preferably between 1 and 10 mM), the conditioned resin separates a number of sugars and sugar alcohols from one another, while still allowing ready desorption from the resin.
