Study of P2P network model based on distributed Agent memory mechanism

Since such problems of P2P network as node frequent offline,lack of trust mechanism and bandwidth limited influence the service quality,a distributed Agent memory mechanism of P2P network model was presented.In this model,the data were divided into several blocks of data,the block service was evaluated after the node visit,and data block content and service evaluation update were stored in the neighborhood node and subsequent node;when the node visits information,according to local strategy,optimize memory,and regularly update and delete for a low service evaluation memory.The model of distributed data blocks through memory and dynamic data updated Agent improves the data availability effectively,stops the spread of the virus document,reduces bandwidth pressure,improves the searching efficiency,and increases the system security and network performance.
