Abstract
In this paper, we propose an upstream resource management propagation (URMP) algorithm for optical burst switching to provide congestion control in the GMPLS control-plane infrastructure. The URMP establishes the transmission control between congested OBS node and the ingress edge routers. The congested node includes an ingress edge router in the URMP algorithm if any of the edge router's label switched paths participate in the congestion. The congested OBS node transmits a URMP message upstream for the involving ingress edge routers, and sets up the URMP states at the OBS nodes throughout the path. Using the URMP states at the OBS nodes, the related congestion events may merge into one congestion. At the receipt of the URMP message, ingress edge routers change their transmissions from asynchronous to slot-based transmission with controlled data rate.
