Application of Cache in P2P Systems

The application of Cache technology is extremely common in the Internet, and this paper combines the cache technology and the P2P technology through designing a kind of interior P2P buffering system in communication architecture, called P2P Cache. With this system, some P2P content will be stored in cache servers, which make users download data from both other peers and cache servers. It gives the users higher download speed and ISPs lower bandwidth cost, does not affect the customer P2P application experience, optimizes the existing network, and reduces the flow rate of export.
