Survey on Contention Resolution Techniques For Optical Burst Switching Networks

摘要

Optical Burst Switching (OBS) is a promising solution for allowing various size data burst to be transported optically over Dense Wavelength Division Multiplexing (DWDM) without optical/electronic/optical conversion. In OBS control packet called control burst is separated from data packet called data burst. A control burst is sent in advance, which configures the switches in the path for data burst. Due to lack of adequate contention resolution technique data burst loss is high in OBS. Contention occurs when more than one data burst try to reserve the same wavelength channel on outgoing link which is a main problem in OBS. In this paper, comprehensive review pertaining the classification of different contention resolution techniques for optical burst switched network has been presented
