Adaptive service analysis for EPON base on working vacation queueing model

We put forward an adaptive service scheme which combines of working vacation and gated scheme to optimize system performance of Ethernet passive optical network (EPON). We investigate the performance of the EPON upstream channel with adaptive service scheme based on the optical fiber communication Multi-point control protocol (MPCP), making use of discrete time working vacation service and gated service scheme vacation queue models. The queue models are analyzed by using method of the matrix-geometric solution method and the exact performance measures are obtained such as average queue length of traffic and average packet delay time which can provide the theoretic basic for EPON system design. Finally, the numerical examples demonstrate the performance of adaptive service scheme is superior to separate scheme.
