The multi-level hierarchical network architecture has been shown to be a scalable and cost efficient solution for large Video-on-Demand (VOD) systems. The predominant operation cost of a hierarchical VOD system consists of network transmission cost and video storage cost. How to minimize the operation cost under several operating constraints is an important issue. In this paper, we proposed several fast video placement algorithms that can achieve near optimal operating cost. We have also proposed a time-variant arrival traffic model with arrival rate matches the statistics gathered from commercial systems.
