基于P2P技术的校园网络应用研究

Research on campus network application based on P2P

P2P对等网与传统的B/S网络模式相比,具有传输速度快、无中心化等优点,因而被广泛的用于校园网的分布式计算、流媒体服务、资源共享等方面;同时P2P技术的应用也带来了网络带宽瓶颈、安全管理等问题。为此,结合P2P技术的原理和特点提出了流量识别和控制、端口及网址过滤等解决方案,并对其在校园网中的应用情况进行了探讨和研究。

P2P technology is a new researching field of campus network. Compared with the traditional technologies, it has the advantages of high speed and non--centralizedness. Thus P2P is widely used in distributed accounting, streaming media service and resource sharing. However, the use of P2P technology brings about many prob- lems to the campus network, such as network bandwidth bottle--neck and security management. Considering the principles, characteristics and models of P2P, the paper suggested the recognition and control of flowing volume, port and address filtering and then discussed the approach of how the P2P technology is used in campus network.
