Asynchronous Variable-Length Optical Packet Switch with Delay-Line Loop Buffers

We propose an asynchronous variable-length optical packet switch that is based on a packet compression scheme and delay-line loop buffers, and evaluate the packet loss probability of the proposed switch through simulation and analysis. Simulation results well the analytical results and show the accuracy of our analysis. When the packet compression ratio is low, optical packet interval regulators are useful to improve the packet loss probability characteristics.
