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： A system for controlling packet forwarding through a point-to-point (p2p) connection between first and second end nodes of a packet network domain having a mesh topology. The system comprises a sub-ring network instantiated in the network domain, the sub-ring network comprising a pair of topologically diverse ring spans extending between the first and second end nodes. Each of the end nodes is controlled to forward packets of the p2p connection through the sub-ring network in accordance with a ring network routing scheme, and an intermediate node traversed by one of the ring spans is controlled to forward packets of the p2p connection through the ring span in accordance with a linear path routing scheme.

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.
