Paper Abstract

To reduce burst drop probability is a key issue in optical burst switching networks for it was connected strongly with the network's overall performance. In this paper, we propose a novel O/E/O conversion and electronic storage based strategy to resolve burst contention. Unlike traditional FDLs based contention resolution which is only able to provide discrete buffering time, O/E/O storage based strategy can offer unlimited buffering time. We propose an intermediate node architecture and corresponding scheduling algorithm called Nearest Available Void (NAV). Simulations show that our novel burst contention resolution enjoys high contention resolution capability and only introduce extremely low extra delay time compared to FDLs based mechanism. The maximum electronic RAM demand is also studied, and the result shows that the demand is comparatively small, which implies the cost of this strategy can be economic.
