Research on Admission Control in Distributed Video-on-Demand Systems
分布式视频点播系统的接入控制研究

Video on Demand(VoD)systems are considered as one of the most valuable services for the next generation broad-bandwidth Internet. To provide high-quality service, the VoD system must employ an admission control module to guarantee QoS, but there are still less research works having been made in this field, especially for distributed VoD systems. In this paper, we mainly focus on distributed admission control for VBR video streams in distributed VoD systems. We firstly discuss different approaches and then two admission control strategies are proposed with experimental comparisons. Our research is also further extended to resource assignment in distributed VoD systems. At the end of this article, we address issues in implementing distributed admission control.
