Burst switching performance study on different traffic priority classes

State key laboratory on fiber optical communication technology The rapid increase of IP service and large capacity in DWDM layer request the all-optical packet delineation and process. Optical burst switching is a promising technology in the future IP/DWDM networks, which provide a feasibility to realize the optical packet switching without optical buffer. Presently the QoS guarantee of OBS depends on the bandwidth control protocol. JET based on RFD generally applied in OBS network is considered in this letter. According to the queuing theoretical model, the performance of one node is studied using simulations. Besides the traditional exponential arriving and service traffic, we analysis the general and self-similar traffic under the same average service time. The analysis and simulating results for different class have important effects on networking performance by comparing the queuing service models
