Abstract

Onboard switching (OBS) is facing resource constraints and special requirements of hardware complexity and scheduling efficiency. By studying the existing OBS fabrics and scheduling algorithms, the Shared Buffer-based Reverse Scheduling (SB-REV) Algorithm is proposed, adopting the shared buffer in the input module (IM) and guiding the IM scheduling with the matching result of the central modules. Theoretical and experimental analysis shows that the SB-REV algorithm greatly improves the resource utilization and scheduling efficiency, while guaranteeing the cell delay and the throughput performance. The SB-REV Algorithm is highly suitable for resource-constrained OBS environment.

Keywords
