This paper pvesents methods fov recovering from channel failures. link failures. and node failures in wavelt%gth-division multiplexed (WDM) p&nt-topoint links and%gnetwo?'ks, with limited wavelength convemion/switching capabilities at the nodes. Different recovery schemes are presented to handle each type of faihme. Each scheme is evaluated based on the network hardware configuration required to support it, and the performance and management overheads associated with fault-recovery.doi:10.1109/infcom.1997.644500 dblp:conf/infocom/GerstelRS97 fatcat:wjoa3bhhafeevovlsyrhx5cfoq
