Abstract: Universality of Peers’ distribution, churning of Peers’ behavior, anonymity of Peers’ transmission and Internet environment change caused by P2P application make traditional network monitoring method invalidly to P2P application. By analyzing the overlay structure and characteristics of Modern Large-Scope Application of P2P network(MLSA-P2P), this paper constructs MLSA-P2P model. Based on the model, it researches searching model and its algorithm of special resource, provides monitoring architecture of P2P network, and solves the problem of monitoring special resources of network.

Key words: P2P network, content monitoring, searching model

摘要： Peer分布的广泛性、行为的动态性、传输的隐匿性以及P2P应用会引起网络环境的变化导致传统网络监控方法无法对P2P应用进行有效监控。针对上述问题，通过分析主流P2P应用，给出当前大规模应用的P2P网络抽象模型及其特征，针对该模型研究特定资源的搜索模型及其算法，建立P2P网络监控体系，实现网络的监控问题。
