Abstract

Motivated by the impressive performance of cost-based scheduling for media streaming, we investigate its effectiveness in detail and analyze opportunities for further tunings and enhancements. Guided by this analysis, we propose a highly efficient enhancement technique that optimizes the scheduling decisions to increase the number of requests serviced concurrently and enhance user-perceived quality-of-service. We also analyze the waiting-time predictability achieved by the new technique. The simulation results show that it can achieve significant performance improvements while providing users with highly accurate expected waiting times.
