Diverse Routing Strategies for On-Demand Lightpath Provisioning in ASON/GMPLS Networks

This paper shows through simulation experiments how using network failures information with dynamic routing in ASON/GMPLS networks can considerably impact on the performance of such network. Three routing strategies are considered differing only in its use of failure information. The performance is evaluated in terms of request blocking probability and availability over two different networks from a sparse one to another highly meshed.
