Throughput Maximization for Optical Burst Switching Networks
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 6
Abstract
Optical burst switching is a one-way reservation technique that provides connectionless transmission services. In OBS Data Traffic Discarded at immediate nodes is retransmitted by the sources. In this project work an attempt is made to improve the performance of Optical Burst Switching (OBS) in situation where OBS performance degrades when the control processing time increases. Three feasible methods to improve OBS performance without significantly increasing the implementation complexity. There are Addition of simple Fiber Delay Lines (FDLs), Random Extra Offset time and Window Based Channel Scheduling (WBS). Additional FDLs can eliminate the negative impact cause by the variation of the offset time between control packets and data bursts. The Random Extra Offset time approach does not require any additional hardware and computational complexity in the nodes. If higher computational capability is available WBS in general can provide better throughput improvement than that of Random Extra Offset time when FDLs are used in the nodes to compensate the processing time.
