Designing Hybrid Optical Switching Network Using Protection Resource
A new hybrid optical switching network based on protection resource named P_HyLABS is presented. P_HyLABS takes advantage of the protection resource (wavelength channels) in optical circuit switching (OCS) network to construct optical burst switching (OBS) network layer,which is combined with the OCS layer into hybrid OBS/OCS switching network. Simulation results show that compared with pure OCS network and OBS network,P_HyLABS takes advantage of the circuit-switched connection of OCS and the statistic multiplexing characteristic of OBS,achieves higher transportation efficiency,accommodates the bursty traffic efficiently and restores part of data transmission even in the case of multiple failures.
