Study of the Technology of Optical Burst Switching Network

With thedevelopmentof thetechnology offiber transmittingandopticalnetwork, the opticalnetwork has been themain backbonenetwork in the high speed broadband networks. In this paper, we discuss threekinds of optical switching technologies and analyse the technical principle of OBS (Optical Burst Switching) network, the switch fabric and some protocols concerned. Because no big breakthrough has not been achieved in the fieldsof optical com- ponentsand optical information processing so far, the technology of OBS, which combines themeritsof OCS (Optical Circuit switching) and OPS(Optical Packet Switching),is a better schemewhich can satisfy the need of the multimedia information, with a large volume and high speed, when switching and transmitting, it will be a core technology in the next generation of optical IP backbone network.
