Abstract

Subject to the QoS-guaranteed playback, the WAN bandwidth needs to allocate the video's peak bit rate if there is no client buffer for regulating the video delivery. To reduce the requirement of WAN bandwidth, the video staging, first proposed by Zhang et al., caches parts of a video content in the video proxy close to clients. Therefore, the video content can be streamed across the WAN with CBR (constantbit-rate) services and its bandwidth requirement is significantly reduced. In this talk, we will review and propose some algorithms designed for video staging.
