A content-oriented web cache poli

摘要

The increasing popularity of network-based multimedia applications poses many challenges for multimedia content providers to supply efficient and scalable multimedia services. Peer-to-Peer (P2P) networks have been shown to be a promising approach to provide large scale video services over Internet since these networks increase scalability and robustness. In this paper, we propose and analyze an object management policy approach for videos web cache in a P2P context, taking advantage of object's meta-data, e.g video popularity, and object's encoding techniques, e.g Scalable Video Coding (SVC). We carry out trace-driven simulation so as to evaluate the performance of our approach and compare it against traditional object management policy approaches. The experiment results show that our proposed approach can improve the performance of the cache substantially.
