Abstract

In this work we propose anycast routing methods to improve the performance of reconfigurable WDM networks under the variations in the IP traffic. We first investigate anycast communication via impairment-aware anycast routing (IAAR); our simulation results show significant improvement in the blocking probability. We also investigate the proposed load-aware anycast routing (LAAR) for the varying traffic model. From the results we observe that LAAR minimizes the lightpath request loss, by dynamically choosing the anycast configuration based on the network load.
