In this paper, the impacts of different scheduling algorithms on buffered crossbar switch (BCS) performances are analyzed. Four BCSs are considered: combined input- and crosspoint-queued (CICQ) switch, output-queued with speed-up N (OQ-N) switch virtual ouput-queued with iterative longest input part first (VOQ) switch and virtual output-queued with longest input port first and with throughput maximization...
We address the issue of contention resolution in optical burst switched networks, and we introduce an approach for reducing packet losses which is based on the concept of burst segmentation. In burst segmentation, rather than dropping the entire burst during contention, the burst may be broken into multiple segments, and only the overlapping segments are dropped. The segmentation scheme is investigated...
