摘要：Peer-to-peer systems generate a major fraction of the current Internet traffic, and significantly increase the load on ISP networks and the cost of running and connecting customer networks to the Internet. It mitigates negative impacts, several previous works within the literature have proposed caching of P2P traffic, but very few have considered designing a caching system to actually do it. Caching P2P traffic is more complex than caching other internet traffic and needs several new algorithms and storage systems. The paper presents the design and evaluation of a entire, running, proxy cache for P2P traffic, referred to as pCache. pCache transparently intercepts and serves traffic from different P2P systems. A replacement storage system is projected and enforced in pCache. Storage system is optimized for storing P2P traffic, and shown to outperform other storage systems. A new algorithm to infer the information required to store and serve P2P traffic by the cache is proposed. Extensive experiments to evaluate all aspects of pCache using actual implementation and real P2P traffic are presented. Based on the analysis, pr oposed a new algorithm, called Least Grade Replacement (LGR), takes recency, frequency, perfect -history, and document size under consideration for Web cache optimization
