Abstract

The average increment and the increasing variability of the traffic to be carried by ASON/GMPLS transport networks will require on-demand bandwidth provisioning in the near future. In this scenario dynamic routing based on traffic engineering techniques is a key issue. This paper deals with dynamic routing in ASON/GMPLS networks based on using network failures information. We define three routing strategies which differ in the use of failure information. Their performance is evaluated by simulation in terms of request blocking probability and availability
