Paper Abstract

OBGP is a distributed protocol, which can provide an inter-domain routing /signaling solution and allow the edge network customer to establish and manage a lightpath though multi-heterogeneous domains. In this paper, we propose a new scheme called DiffServ-aware OBGP by extending the OBGP. It can resolve the open problems of customer access admission in domain and the conflicting resource requests by distinguishing the priority of customer requests. The paper depicted the basic extension requirements for current OBGP message and the end-to-end lightpath establishment process at length. The simulation shows that the new scheme can establish adaptive end-to-end lightpath according to the request of customer and the higher priority requests have more probability of establishing lightpath when resource competition happened.
