Abstract
A packet network linear protection method, a network, and a node in a dual or multi-home configuration include designating each of a plurality of home nodes in the dual or multi-home configuration as a working home or a protect home; designating each link between each of the plurality of home nodes and an end node in the dual or multi-home configuration as active or standby; operating a protection switch state machine based on an associated linear protection protocol at each of the plurality of home nodes and the end node; communicating protection messages to each of the plurality of home nodes from the end node; and communicating protection states in an associated protection switch state machine by each of the plurality of home nodes to other home nodes and to the end node.
