Abstract :
The key performance bottleneck for a video-on-demand (VOD) server is bandwidth, which controls the number of clients the server can simultaneously support. Previous work (Carter & Long, 1997, 1999) has shown that a strategy called “stream tapping” can make efficient use of bandwidth when clients are not allowed to interact (through VCR-like controls) with the video they are viewing. In this paper, we present an interactive version of stream tapping and analyze its performance through the use of discrete-event simulation. In particular, we show that stream tapping can use as little as 10% of the bandwidth required by dedicating a unique stream of data to each client request
