Research on Improved Burst Assembly Algorithms in OBS network

With the rapid development of WDM technology,network bandwidth increases dramatically,thus resulting in the bottleneck problems of network nodes.Due to the immature technology of optical device,a relatively simple transition technology—optical burst switching (OBS) appears,and becomes a switching mode with the most application prospects and technical advantages.Burst assembly algorithms is one of the key technologies of the OBS edge nodes.Based on the burst assembly algorithms,the paper describes four improved algorithms.The analysis shows that the reasonable burst assembly algorithms can reduce the processing burden of the switching node,achieve traffic shaping and provide QoS,and raise the overall performance of the OBS network.
