A method and system for operation of a resilient closed communication network
without
a dedicated protection network segment. The method uses a resilient closed communication
network with at least one communication ring. The method includes the steps of
receiving a data packet from a first external network at a first distributing station
connected to the network, identifying a second distributing station connected to
the network from which the data packet is to be forwarded to a second external
network, and determining functioning routes from the first distributing station
to the second distributing station. The method also includes the steps of selecting
an optimal route among the functioning routes and sending the data packet from
the first distributing station to the second distributing station using the optimal route.
