Overview: Video-On-Demand IP (VOD) is one of the best known examples of "Next-generation" Internet applications cited as a goal by networking and multimedia researchers. Without empirical data, researchers ha have generally relied on simulated models to drive their design and developmental efforts. This paper presents one of the first measurement studies of a large VOD system, using data covering 219 days and more than 150,000 users in a VOD OD system deployed by China Telecom. This study focuses on user behavior, content access patterns, and their implications on the design of multimedia streaming systems. The results also show that when used to model the user arrival rate, the traditional Poisson model is conservative and overestimates the probability of large arrival groups.
