IP over WDM Module for the NS-2 Simulator

Abstract

This paper presents the design of an IP over WDM module for the ns-2 simulator. The module make available the evaluation of QoS metrics, such as blocking probability and delay in IP over WDM networks. The module allows simulation of networks with traffic grooming, single and multi-hop routing, protection and restauration and global reconfiguration. This module is intended to be a valuable tool for research in IP over WDM networks mechanisms.
