Abstract
A method for handling communication failures in a network, which includes provisioning first and second multipoint-to-multipoint communication services over respective first and second alternative sets of links that connect the endpoints in a network. Each of the sets connects network nodes which provide physical layer resources for the links. The communication service is provided to the endpoints over the first set of links using the first service. Upon detecting a failure in the first set of links, the physical layer resources of the links in the first set are deactivated by the network nodes, in order to lose their connections. Responding the loss of connection, the communication service automatically transfers communication to the second set of links.
