中文摘要	The authors proposed a novel mechanism based on optical border gateway protocol (OBGP) that implements inter-domain routing in optical mesh networks. Based on an idea of minimum-hop optimal path and a bypass routing during the request course of lightpath setup phase, they achieved the procedure of dynamic and distribution lightpath establishment efficiently in optical networks, which results in a lower blocking probability than before. They also made resource reservation and configured hardware with a "parallel signaling" mode, which can reduce the end-to-end delay. An experiment of this mechanism using optiman network simulation tools has been presented, which has shown that our study can decrease blocking probability on condition of heavy traffics and make network performance better. It also demonstrates that the three factors, such as network scales, number of wavelengths and traffic loads, have influenced on the network performance. The analysis indicates that a value related to the change of blocking probability approximates the product of end-to-end delay and network scales.
