Extensive interest in using public networks has increased the traffic volume and encouraged network providers to employ new technologies for better quality of service and traffic protection. Wavelength division multiplexing (WDM) is a new technology satisfying the growing demand for network capacity. Multiprotocol label switching (MPLS) provides a mechanism for traffic protection in IP networks. In this research, we have focused on recovery techniques and restoration methods that operate at label switch paths (LSPs) in MPLS networks. Mathematical analysis as well as simulation programs for evaluation of different restoration techniques are given.
