Object-Oriented Modeling and Simulation of Optical Burst Switched Mesh Networks

Abstract

This chapter presents an object-oriented approach for the development of an optical burst switching (OBS) simulator, called OBSim, built in Java. Optical burst switching (OBS) has been proposed to overcome the technical limitations of optical packet switching and optical circuit switching. Due to the high costs of an OBS network infrastructure and a significant number of unanswered questions regarding OBS technology, simulators are a good choice for simulation and estimation of the performance of this kind of networks. OBSim allows the simulation and evaluation of the performance of IP over OBS mesh networks. A detailed description of the design, implementation and validation of this simulation tool is presented.
