Minimizing Protection Cost for High-Speed Recovery of Mission Critical Traffic in WDM Mesh Networks
Network survivability depends on the choice of recovery scheme and offers challenging tradeoffs in terms of recovery speed, cost, and management complexity. To allow more efficient operation of backbone networks, service differentiation based on reliability requirements have been proposed. However, the cost for protecting mission critical data using high-speed recovery schemes can still be expensive. The authors previously described an online protection scheme called Streams Protection that allows fast recovery and low data loss with little extra capacity. In this paper, the authors present a capacity optimization technique using the Streams Protection scheme for use with static traffic demands consisting of high-priority traffic.
