摘要

E-learning service is getting increasingly popular, especially the multimedia content educations. To distribute content to end users, two different technologies - Content Distribution Network (CDN) and Peer-to-Peer (P2P) network - have been proposed. However, both technologies have their own limitations: CDN servers are expensive to deploy and maintain. Under P2P network, anyone could share his content regardless of the copyright. In this paper, a new concept of integrating both CDN and P2P technologies into a replication-aware CDN-P2P architecture has been proposed. We propose a two-step selection approach on landmark-based selection algorithm to find the nearest replica-cache server and peer-caches to download content in this architecture. Furthermore, recent studies have supported the claim that network coding technology is beneficial for large-scale P2P content distribution. Herein, we show how to apply network coding technology to distribute content so that the content provider's rights can be protected.
