Delay Sensitive Smoothed Round Robin (DS2R2) scheduler for high-speed optical networks

Abstract

Smoothed Round Robin (SRR) is an O(1) scheduler that efficiently schedules flows based on flow granularity leading to short-term fairness. We propose DS2R2 – Delay Sensitive Smoothed Round Robin Scheduler that enhances SRR by adhering to delay constraints of flows. Scalability and performance issues of DS2R2 for high-speed optical networks are considered.
