Paper Abstract

In an asynchronous optical packet switching network, contention occurs at a node whenever two or more packets are trying to leave the node from the same output port on the same wavelength. As a means of contention resolution, fiber delay lines (FDLs) are commonly implemented in optical buffers. This paper presents an analytic model to study single-wavelength FDL buffer systems with finite waiting places. Considering the delay quantization in FDLs the deference between waiting time and delay time is discussed detailedly and then the packet lengths are modified. Analytic results of the queuing performance can be figured out for the finite FDL buffer system. Accuracy of the proposed model is finally validated through numerical simulation.
