A method forward Ethernet frames at a node in a network supporting an implementation of shortest path bridging (SPB) protocol is disclosed. The method starts with a shortest path computation for the node (referred to as the computing node). The shortest path computation selects at least a shortest path to each destination node in the network, where a neighboring node on the shortest path to reach each node is recorded. Then it computes a downstream loop-free alternate (LFA) node for a destination node, where the LFA node is downstream of the computing node but not on the selected shortest path to the destination node from the computing node. Then when connectivity to the neighboring node on the computed shortest path is detected to be abnormal, the node forwards an Ethernet frame with a destination media access control (MAC) address corresponding to the destination node through the LFA node.
A method to forward Ethernet frames at a node in a network supporting an implementation of shortest path bridging (SPB) protocol, wherein each Ethernet frame contains a source and a destination media access control (MAC) address, wherein the node contains a plurality of ports to receive and forward Ethernet frames, wherein the node contains a filtering database (FDB) to guide Ethernet frame forwarding, wherein FDB update is coordinated through a digest exchange between the node and one or more neighboring nodes, and wherein the FDB contains a plurality of mappings of ports to MAC addresses, the method comprising:
A non-transitory computer-readable storage medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations in an electronic device to forward Ethernet frames at a node in a network supporting an implementation of shortest path bridging (SPB) protocol, wherein each Ethernet frame contains a source and a destination media access control (MAC) address, wherein the node contains a plurality of ports to receive and forward Ethernet frames, wherein the node contains a filtering database (FDB) to guide Ethernet frame forwarding, wherein FDB update is coordinated through a digest exchange between the node and one or more neighboring nodes, and wherein the FDB contains a plurality of mappings of ports to MAC addresses, the operations comprising:
