摘　　要：P2P(Peer-to-Peer,点对点)下载技术是校园网带宽控制的技术热点,此技术的应用占用了校园网大量的出口带宽,80%的出口资源被20%的用户所占用,造成了校园网带宽的瓶颈。分析P2SP(Peer-to-Sever&Peer)技术原理,结合校园网络的设计及使用的特点,提出了利用基于时间的ACL(Access Control Lists,访问控制列表)来控制用户访问P2SP资源索引服务器以控制下载流量的具体实现方法。校园网出口实际测试结果显示,本方法能准确控制P2SP流量。P2P is used frequently in campus network technology. The application of this technology takes up a large number of bandwidth in a campus network. 80% of resources are occupied by 20% of users, which results in a bottleneck of a campus network bandwidth. According to the principle of P2SP technique and the characteristics of a campus networks design and use, this paper proposes concrete approaches to limit the number of P2SP resource server users based on ACL, which is used to control the net traffic.
