A Contention Avoidance Scheme for Optical Packet Switched Networks

Abstract

Optical Packet Switched(OPS) networks combine the potentials of the high capacity optical technology with the flexibility of packet switching. OPS networks provides the finest granularity and highest multiplexing gain in its segment and can be considered as one of those technologies which has the potential to utilize the high bandwidth available through DWDW. However, optical RAMs are still not successful, wavelength converters are expensive and deflection routing is topology dependent. Hence, high losses due to contention occlude the benefits offered by these networks. My work basically aims at utilizing the capabilities of electronics to queue and schedule the traffic using the prior knowledge of the link loads in such a way that the packets experience less contention while travelling through the intermediate core nodes.
