摘要： In one embodiment, a communications distribution process maintains at least two pseudowires through a network such that the pseudowires share a burden of delivering data through the network. The communications distribution process receives feedback data concerning operation of each pseudowire. The communications distribution process utilizes the feedback data to distribute communications to the common destination across each of the pseudowires. Additionally, the communications distribution process utilizes the feedback to establish at least one new pseudowire, in addition to the first pseudowire and the second pseudowire, for transmission of data traffic.

摘要： A method and apparatus for restoring a virtual path are disclosed. The method includes identifying an alternate physical path and determining whether the alternate physical path is able to support the virtual path by determining whether each node of the second subset of nodes has sufficient resources necessary to support the virtual path. The virtual path is over a physical path in an optical network, and the optical network includes a number of nodes. The physical path includes a first subset of nodes of the nodes. The alternate path includes a second subset of nodes of the nodes and is between a first node and a second node of the first subset of nodes.

摘要： A system and method for introducing in-band network management packets (INMPs) in a Multi-Protocol Label Switching (MPLS) network. MPLS is an emerging technology, which integrates Internet Protocol (IP) routing with label switching techniques. MPLS intends to provide new capabilities in the area of traffic engineering for IP networks. These traffic engineering capabilities will have to be combined with a set of complementary operation, administration and maintenance (OA&M) functions for effectively managing and operating MPLS-based networks. This invention uses INMPs for carrying OA&M information to label switching routers (LSRs) for effectively managing and operating MPLS-based networks. This invention also includes techniques for distinguishing INMPs from user packets in an MPLS network. This invention further includes using a predetermined code in a shim header of an MPLS packet to determine whether an MPLS packet is an INMP or a user packet. The predetermined code may be provided in an experimental field or a time-to-live field in the shim header of the packet. Alternatively, a label may be reserved for distinguishing an INMP from a user packet.

摘要： Systems and methods for communicating on a richly-connected multiprocessor computer system using a pool of buffers for dynamic association with a virtual channel. Packets are communicated in a multiprocessor computer system having a large plurality of processing nodes interconnected by a defined interconnection topology, in which a communication from a source processing node to a target processing node may pass through one or more intermediate nodes en route to the target processing node. A set of virtual channels is associated for each link in the interconnection topology. A first subset of buffers is dedicated for fixed correspondence to virtual channel identifiers, and a second subset of buffers is dedicated for dynamic allocation and assignment to virtual channels.

摘要： A packet router in a label switching system includes a logical router configuring module for logically dividing a label switching router (LSR) into a plurality of LSRs each having a label switching function, and a module for specifying, when setting a label switched path on the basis of an explicit route specified, a port or a port group of an egress node.

摘要： A system of hitless restart in a network, where at least one node in the network provides routing control distributed among ingress ports (ingress cards) and egress ports (egress cards), is disclosed. With distributed routing control, each ingress card has its own routing-control software and each egress card has its own routing-control software. When the routing-software at an ingress port or an egress port of a node is restarted, current connections traversing a restarting ingress card or a restarting egress card continue to function normally during a restart period without data loss. The disclosed system is tailored to a multi-protocol label switching (MPLS) network employing distributed-resource-reservation-protocol traffic engineering (RSVP-TE). The system relies on messaging between ingress card control planes, ingress card data planes, egress card control planes, and egress card data planes of a restarting node.
