28 September 2006A novel adaptive routing policy for photonic MPLS routers
NTT has proposed a photonic MPLS router (PMR) to support IP over optical layer networks. There are two routing policies implemented in PMR, which both consider IP layer and optical layer resource separately. We found in the PMR architecture, PSC port is significant resource. In this paper, we propose an adaptive routing policy for PMR. Our routing policy has two features: integrated routing and PSC port number sensitive. Simulation results show that the adaptive routing policy has a better overall performance in resource utilization.
