An Efficient Admission Control Mechanism for Optical Burst-Switched Networks

This paper proposes the Load-Level-Based Admission Control mechanism (LLAC) in order to provide service differentiation for optical burst-switched networks. The LLAC mechanism admits bursts of a given service class according to the network load and a class-associated parameter. Based on this parameter, called load level, the proposed mechanism differentiates the burst blocking probability experienced by each service class. The authors develop an analytical model for the proposed mechanism and evaluate its performance for different configurations through mathematical analysis.
