Improving QOS Using Virtual Topology Design for OBS Switching Network
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 4
Abstract
In WDM Networks, OPS and OBS provides efficient communications for many internet applications such as high performance scientific computations, video conferencing by combining hundreds of high speed wavelength channels onto a single fibre for parallel transmission.OBS uses control messages for reserving resources and configuring switches which lead to packet loss and delay. In this paper we address the issue like packet loss, delay and network diameter by designing virtual topology for Optical burst switching. We also propose shortest path algorithm to reduce the number of intermediate nodes and to reduce packet loss and delay, P-routing algorithm is implemented.
