Restoration and Spare Capacity Assignment in WDM Networks
WDM technology is an emerging technology to enhance the capacity of the existing fiber plant. The throughput is in the order of tens or hundreds of Gbit/s, even in the order of Tbit/s [1,2]. This urges on finding adequate and cost effective means to survive failures in the network. In this paper restoration techniques in WDM networks are discussed and their spare capacity requirement is compared.
