Abstract

Performance of 1:1 path protection times in the range of 100-200 msec are reported with optimum design parameters implemented in a large continental optical network. Protection time depends heavily on the network (size, topology, length of the traffic demands) under consideration, the algorithm used for fault mitigation, and switching and processing times at nodes. Standardized generalised multiprotocol label switching (GMPLS) signaling, routing, and LMP protocols can be used to implement a variety of desired protection and restoration mechanisms for traffic recovery to meet various service requirements.
