摘要： A system for controlling packet forwarding through a dual-homed connection between first and second network domains, the dual-homed connection including two peer nodes connected to the first and second network domains. A sub-ring network is instantiated in the first network domain, and includes at least two nodes connected in a linear topology between a pair of end-nodes. Each end-node corresponds with a respective one of the peer nodes. A virtual link through the second network domain for conveys traffic of the sub-ring network between the peer nodes, and closes the sub-ring network to define a ring topology. Each of the nodes of the sub-ring network is controlled to forward packets of the sub-ring network in accordance with a ring network routing scheme.

摘要： A method and system provide in-band protection switch signaling in a communication system arranged as a point-to-multipoint tree. The point-to-multipoint tree includes a root node communicatively coupled to a plurality of leaf nodes through both a working link and a protection link. Data is transferred through a current link of the point-to-multipoint tree. The current link is either the working link or the protection link. A fault is detected in the current link in the point-to-multipoint tree. Each leaf node in the point-to-multipoint tree is notified of the fault using the current link. Upon receiving the notification, the root node and each leaf node switch to the other link of the working link and the protection link.

摘要： A unique RVID is used for each spoke node to identify traffic flowing from that spoke node to the hub and from the hub to the spoke. Spoke nodes perform MAC learning on any frame containing their assigned unique RVID and only bridge traffic received on the ring to a client port if the traffic contains their assigned RVID. Thus, MAC learning at the spoke is localized to client routes, or to routes of interest that pass through the hub. The hub node learns C- VID/RVID - ringport bindings for traffic on the ring. When a frame is received on the ring, the hub will use the C-VID and RVID to determine the I-SID and forward the traffic onto the external network. When a frame is received from the external network, the hub node will use the I-SID & C-VID to determine the RVID of the spoke node, and then use the C-VID & RVID to determine, from its forwarding database, which ringport should be used to output the frame.

摘要： Described are a system and method for managing a service across an optical network over a dedicated circuit between a first and second service termination points. Each service termination point generates a service performance report message. Each service performance report messages has information related to a performance of the service as determined by the service termination point generating the message. The service termination points exchange the service performance report messages over a service management channel to enable an assessment of the performance of the service based on the service performance report messages from both service termination points. Through access to and use of the service management channel, service providers can implement an edge management model or a core management model for measuring the performance of their services with respect to service level agreements governing those services.

摘要： A method and system for rerouting data in a communication network ring. The ring includes a plurality of nodes and a plurality of links. Each node includes a first port and a second port. Each first port is connected to a neighboring second port through a link of the plurality of links. The topology of the communication network ring is discovered and a forwarding database table is populated with static entries according to the discovered topology. Upon receiving notice of a failed link, which includes a source address of a node adjacent to the failed link, the topology and the source address of the node adjacent to the failed link is used to reconfigure the forwarding database table. Data is forwarded using the reconfigured forwarding database table without flooding the ring.

摘要： A system, method and/or station that provides for spatial reuse over a resilient packet ring (RPR) network. A sublayer in a station on an RPR network tracks associations between MAC addresses of bridges on the RPR network and remote addresses in an association database. Frames addressed to a remote destination may be sent directly to the associated MAC address. A sending station uses an extended frame format for sending frames to remote addresses. If the association database in the sending station specifies an associated bridge MAC address local to the RPR network then the extended frame is addressed to the specified MAC address and flooding is disabled. If there is no association in the database, then the sending station uses a reserved group address and floods the RPR network. The sublayer "learns" associations based upon frames received from stations that also have a spatially aware sublayer.

摘要： Interworking an Ethernet Ring network with an Ethernet network with traffic engineered trunks (PBT network) enables traffic engineered trunks to be dual homed to the Ethernet ring network to enable for protection switching between active and backup trunk paths in the PBT network. In one embodiment, the active path will terminate at a first bridge node on the Ethernet ring network and the backup path will terminate at a second bridge node on the Ethernet ring network. Trunk state information is exchanged between the bridge nodes to enable the bridge nodes to determine which of the active and backup paths should be used to forward data on the trunk. Upon a change in trunk state, a flush message is transmitted on the Ethernet ring network to enable the nodes on the Ethernet ring network to relearn the path to the new responsible bridge node.
