| Abstract: | Both Content Distributed Network and P2P architectures have been proposed.However,each kind of architecture has its own lcharacteristics,In this paper,a new design of CDN based on P2P networks autonomy cache system architecture was presented,the proposed autonomous region in the smart cache replacement issue and gives the Intelligent cache replacement method and the replacement algorithm of double .The simulation experiments can be found to computing low complexity of the relatively and high cache hit a relatively rate of the keywords to achieve cache replacement. |
