Survey of Burst Integrity Protocols for Optical Burst Switched Networks

Optical burst switching is one of the most promising technologies in the optical domain. In OBS network, bursts of data consisting of multiple packets are switched through the network all optically. A burst header packet is transmitted ahead of the burst in order to configure the switches along the burst's route. The burst header and the bursts are separated at the source, as well as subsequent intermediate nodes, by an offset time. Even though OBS has a greater advantage with high speed data transfer but if suffers from security vulnerabilities. Once the burst header is redirected by the malicious node, the burst may redirect to fake destination. In this paper, we discuss the various burst integrity algorithms for optical burst switched networks. Moreover we conclude that Secure Hash Algorithm finds to be an optimal solution for burst integrity.
