Constant data length retrieval for video servers with variable bit rate streams

Abstract

We define a novel retrieval algorithm for variable bit rate video streams called GCDL that reads the video data from the disk as constant size data blocks. We formulate for GCDL a deterministic admission control criterion and evaluate its performance. Compared to existing retrieval algorithms, GCDL decreases the buffer requirement and start up latency while admitting the same number of clients.
