Cache Replacement Strategy Based on Energy Model for Interactive Streaming Media

A new energy model based cache replacement strategy is proposed for interactive streaming.First,a division and record method of media segments is presented to record the information of users' visits and the expression of content popularity is presented by the energy model.Then,adopting exponential cache admission/release policy,a new benefit function is designed to control the cache replacement.Simulation results show that the energy model strategy outperforms the traditional segment-based cache algorithms.
