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.
