Architecture of GMPLS-based optical burst switching networks and its performance simulations

The efficient integration and cooperation between optical burst switching (OBS) and generalized multi-protocol label switching (GMPLS), using GMPLS to provide good technical method for control and management of OBS networks, are studied in this paper. At first, the architecture of GMPLS based OBS networks is proposed. Then two spare resources sharing policies are described, and the transmission mechanism of GMPLS control information and optical burst data and the node functional model of GMPLS based OBS networks are expatiated. More discussions in this paper focus on the signalling, routing, link management which could enhance and extend the OBS capability based on GMPLS. At last, some simulations are carried out to evaluate the performance improvement of GMPLS-based OBS networks in terms of packet drop probability. The results show that the integration of GMPLS and OBS can improve the performance of OBS networks.
