“…In order to better utilize network resources, low-speed packet LSPs should be efficiently merged at some transit nodes into highspeed lambda LSPs. Thus, traffic grooming [3] is motivated by the need to efficiently multiplex predominantly IP traffic flows on to higher capacity wavelength channels.…”

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.
