OBS的组装算法及对TCP性能影响

Optical burst switching (OBS) technology has a promising development because of combining the advantages of optical circuit switching(OCS) and optical packet switching(OPS) whose faults have been avoided. The main theory and the network’s architecture of OBS are presented. A novel assembly algorithm is proposed, based on the investigation of two effects of burst assembly on TCP transmission (namely delay penalty and correlation gain). This assembly algorithm perfectly combines linear estimation of burst length and dynamic regulation of assembly period, and simulation results show it can reduce delay penalty and enhance correlation gain, and thus improve TCP transmission over OBS.
