In order to take full advantages of optical circuit switching (OCS) and optical burst switching (OBS) technology and enhance the capability to cope with network failures,a new OCS/OBS hybrid optical switching network is presented. The OCS layer of the proposed network is composed of light paths which are established according to the traffic demands between all the source-destination nodes. And the remaining wavelength channels on each physical link are used to build the OBS layer. When one or more light path breaks down due to network failure,the affected data packets can be assembled into bursts and transported through the OBS layer. In normal operating scenario,OCS layer carries most of the traffic. If bursty traffic overwhelms the transmission capacity of OCS layer,the excess part of traffic can be sent through OBS. Simulation results show that,compared with the pure OCS network with restoration and pure OBS network,the proposed hybrid optical switching network can achieve lower packet loss rate under different network failure scenarios and can accommodate bursty data streams more efficiently.
