Abstract:
1. A node for a link state protocol controlled Ethernet network, the node comprising: at least one network interface; a data plane coupled to the at least one network interface; at least one control plane processor coupled to the data plane; and at least one memory element storing instructions for execution by the at least one control plane processor, the instructions comprising: instructions executable to assign a respective link identifier to each adjacency or output link of the node; instructions executable to generate and transmit, on the link state protocol controlled Ethernet network, a link state routing protocol link state advertisement indicating a list of adjacencies or output links and corresponding assigned link identifiers; and instructions executable to compute at least one detour route using the link identifiers of neighboring nodes to determine at least one one-hop detour around adjacencies for use in the event of a failure involving at least one of the adjacencies.
