Abstract :
For optical fiber systems carrying multiple Gb/s, the failure of a key fiber-optic system can result in huge loss of bandwidth. Failure immunization technology for network service survivability (FITNESS) is proposed method to restore fiber networks in a distributed fashion using broadband digital cross-connect systems (B-DCS) in a synchronous optical network (SONET). With intelligent B-DCS cross-connecting at the synchronous transport signal level 1 (STS-1), level, FITNESS unites this distributed intelligence into a single coherent parallel-processing entity to restore the network in under two seconds. Some performance results are obtained through software emulation using a real LATA model are presented
