Optimum Cache Design for Reducing P2P Traffic

Abstract (in Japanese) (See Japanese page) 
(in English) Traffic caused by P2P services dominates a large part of traffic in the Internet, so reducing the P2P traffic within the networks is an important issue for ISPs. To reduce the P2P traffic, it is effective for ISPs to implement cache devices at some ports of routers and reduce the hop length of P2P flows by delivering required contents from caches. However, the design problem of caches for P2P traffic has not been well investigated although the effect of caches strongly depends on the cache locations and cache capacities. In this paper, we propose an optimum design method of caches for P2P traffic minimizing the total amount of P2P traffic based on the dynamic programming, assuming that transit ISPs provide caches at peering points with stub networks. Moreover, we numerically show the results of applying the proposed cache design method to 31 actual ISP backbone networks.
