Quality of Service in an Optical Burst Switching Ring

Abstract

Several access protocols are proposed to support different service classes in an optical burst switched ring. Their performance is evaluated through simulation. Various performance metrics such as throughput, utilization, burst loss rate, end-to-end delay and fairness are used to analyze the behavior of each protocol.

“…The common approach to support the DiffServ traffic in an output port of a router is to use a shared First-Come-First Served (FCFS) buffer for each class, e.g., [8][9][10][11][12][13]. Here, the same-class packets from different sources are all saved in a shared buffer.…”
