Time Delay Analysis in Wavelength Router Optical Burst Switching (WR-OBS) Networks

摘要

The concept of wavelength router optical burst switching (WR-OBS) aims to allow the access of the bandwidth without using wavelength for routing, instead, it provides guaranteed delivery of optical data bursts to the destination. However, there are some inherent "wasting" times at edge router which influence negatively on some delay sensitive applications. This paper presents a comprehensive analytical study for all significant latency aspects. It can be considered as a guide line to network designer to make the required optimization. The main latency sources are investigated through two different network sizes.
