A method for translating control messages between a network manager and a router. The method includes intercepting an input command message intended for the router, where the router partitioned into a plurality of logical router partitions, and the input command message expressed in terms of logical router partitions. Each logical router partition expression of the input command message is translated into a physical router expression, and the input command message, including any translated expressions, is propagated toward the router.

In a telecommunications network, such as an optical mesh network, satisfying a demand from a start node to an end node, the network is automatically provisioned from a service path to a restoration path after a failure occurs in the service path. Each affected node in the network eventually receives an indication of the occurrence of the failure in the service path. If the node is an intermediate node of the service path, then the node transmits a failure message to its next node along the service path. If the node is the end node of the service path, then the node transmits a restore message to its previous node along the restoration path. If the node is an intermediate node of the restoration path, then the node transmits a restore message to its previous node along the restoration path. In addition, the node reconfigures its cross-connect for the transition from the service path to the restoration path.
