Diffserv Implementation By A Balking Mechanism In Delay-line Buffering

In this paper we address the problem of providing delay-line buffers with the capability to differentiate services in optical packet switching networks. A simple and efficient policy for acceptance and discarding of optical packets is proposed and its analytical model is presented. The model enables the exact calculation of packet loss probability and average delay for Poisson arrivals and any packet length distribution. The buffer performance as predicted by the model is compared with simulations for Pareto packet length distribution.526842688Xiao, X., Ni, L.M., Internet QoS: A big picture (1999) IEEE Network, 13, pp. 8-18. , MarYoo, M., Qiao, C., Dixit, S., QoS performance of optical burst switching in IP-over-WDM networks (2000) EEE J.
