Abstract

This work proposes a new wavelength converted broadcast-selective (WCBS) buffer structure. It can deliver each packet to different delays, which enables flexible management of the buffered packet flows. By rearranging the packets leaving queue, the highest priority packets can leave first and in preemption process without being affected by the former queue. Furthermore, we use the WCBS buffer structure to construct an OPS node in output-buffered pattern. The packet loss and delay performances are studied under different traffic loads at different WCBS dimensions. The result shows that the performance of high priority packets is improved effectively.
