Patent ID: 7012887

Claim:
A method for restoring a diversely routed circuit in a mesh network, comprising the steps of: initiating and sending one or more triggers in at least one of a first direction along said first path, a second direction along said first path, a first direction along said second path, and a second direction along said second path; receiving one or more triggers at one of a destination node and a source node of a first path, said one or more triggers indicating a path failure; determining whether a switch has occurred at one of said source and destination nodes, and calculating according to a predetermined algorithm whether to switch one of said source and destination nodes to a second path; when said algorithm calculates that a switch is required and that said switch has not already occurred, switching from said first path to a functional second path, prompted at least partially by said one or more triggers, to restore said circuit; and restoring said first path to a functional path.
