Performance Analysis of Scheduling Algorithms in Optical Burst Switching Networks
Optical Burst Switching (OBS) is developed as an alternative switching technique for next generation optical networks, which combines advantages of both Optical Circuit Switching (OCS) and Optical Packet Switching (OPS) and avoid disadvantages. There are certain performance related issues such as scheduling, burst aggregation, contention resolution and Quality of services that needs to be addressed in OBS. Scheduling of data burst in an optimal way is one of the key problem in optical burst switched networks. Another major issue is contention, contention occurs when more than one data burst try to reserve the same wavelength channel on an outgoing link. In this paper, comprehensive review pertaining the classification of different scheduling algorithms for optical burst switched network has been presented.
