Caching the P2P Traffic in ISP Network
The rise in Peer-To-Peer (P2P) networking has been tremendous in last several years. P2P traffic has significant impact on ISPs as it accounts for more than half of all traffic. Although many methods have been proposed to manage P2P traffic, little effort was spent on the deployment issues. In this paper, the authors have studied how to deploy P2P traffic cache devices in the backbone network to maximize the benefit of the ISP. A novel model is proposed to evaluate the benefits of deploying cache devices on different links. Guided by their model, two algorithms were developed to instruct the deployment of cache devices in the network.
