Performance analysis of a hybrid optical-electronic packet switch supporting different service classes

Résumé

As a solution to the high energy consumption caused by numerous O-E-O conversions in electronic switches, and the poor contention handling of all-optical switches, we investigated a hybrid switch that supplements optical switching with an electronic buffer. Our study takes into account reliable, fast and default packets that have different requirements of QoS performance criteria. We show, by simulations, that with only a few electronic ports to the buffer, the hybrid switch significantly improves the PLR and the sustainable system load compared to an all-optical bufferless switch and meets the different packets classes' requirements. In addition, we quantified the considerable decrease of O-E-O conversions as well as the switching latency achieved by the hybrid switch compared to an electronic switch
