Contention Handling in SMP Based Networks

摘要

Nodes and methods are disclosed for protection and restoration in the event of multiple failures for multiple paths involved for the same service in shared mesh networks, including, a method comprising the steps of storing, in non-transitory memory of a first node in a shared mesh network having a plurality of connections through the shared mesh network, records of global contention handling priority values of the plurality of connections; detecting a first signal from a second node requesting activation of a first connection of the plurality of connections, and a second signal from a third node requesting activation of a second connection of the plurality of connections, the first and second connections having overlapping requirements; determining that the second connection has a higher global contention handling priority value than the first connection based at least in part on the records; and activating the second connection.

1. A method comprising the steps of:
storing, in non-transitory memory of a first node in a shared mesh network having a plurality of connections through the shared mesh network, records of global contention handling priority values of the plurality of connections; detecting, by circuitry of the first node, a first signal from a second node requesting activation of a first connection of the plurality of connections, and a second signal from a third node requesting activation of a second connection of the plurality of connections, the first and second connections having overlapping requirements; determining, with circuitry of the first node, that the second connection has a higher global contention handling priority value than the first connection based at least in part on the records; and activating, with circuitry of the first node, the second connection.
