Performance analysis of overlapping shared segment protection in Store-and-Transfer WDM networks

Abstract

In this work, we investigate overlapping shared segment protection under continuous and TDM-mode sliding scheduled traffic model and compare its performance with that of shared path protection under sliding scheduled traffic model in Store-and-Transfer WDM Networks. Simulations show the following: Under continuous sliding scheduled traffic model, shared segment protection has 12% lower blocking rate than shared path protection and if number of requests is large, shared segment protection requires 20% more storage than share path protection.
