Abstract :
The paper addresses the problem of providing QoS management for an optical packet switch. In particular, we propose the simple prioritized buffering algorithm (SPBA) for prioritized buffer management, which aims to guarantee different packet loss probabilities to different packet streams. In contrast to other solutions, SPBA does not need any resource reservation or threshold dropping, but only makes use of priority scheduling. A theoretical model of SPBA with K classes of service applied to an optical packet switch with fiber-delay line buffers and tunable wavelength converters is presented. The analytical model is verified by simulations.
