2、隐患等问题，妨碍了正常的网络业务的开展。P2P 技术占据着网络带宽的绝大部分，如何控制 P2P 流量，是我们在享受 P2P 带来的便利的同时必须要考虑的一个问题。因此，实现 P2P 流量的有效识别和控制已经成为急需解决的问题。论文正是在这种背景下，针对 P2P 流量特点展开的研究工作。论文主要包含了以下内容：1、对 P2P 技术进行了研究。分别对 P2P 技术定义、 P2P 技术的四种网络拓扑模型、P2P 技术特点、 P2P 关键技术、P2P 相关协议及应用进行了分析研究。2、详细分析了 P2P 流识别中存在的问题，着重研究和比较了当前存在的几种P2P 流识别方案的工作原理，以及其在 P2P
3、流识别过程中的特点和存在的问题同时介绍了几种流量控制技术和管理策略。3、针对现有 P2P 流量检测方案存在的不足，提出了一种改进后的综合检测方案，在新的方案中采用流量特性检测和深度包检测等综合识别的检测方式。该方案克服了当前的几种 P2P 流识别方案的缺点，有效地提高了 P2P 流的识别率。4、在论文提出的方案基础上设计了一个 P2P 流量识别与管理系统，该系统可以实施有效的识别及控制。关键词：对等网络、P2P 流量识别、深度包检测、 P2P 流量控制校 园 网 问 题 解 决 方 案 河南大学 信息系 2010 本科毕业论文IIAbstractWith the development of
4、network technology and peoples demand for the network, a technology (P2P) back to those days peoples attention, and soon became one of the most popular network applications. The investigation showed that, P2P has been quietly operating the Internet business accounted for 60% of a total 80%, a killer
5、 of broadband Internet applications. P2P traffic is in the Intemet an enormous role in promoting the same time, it also brings a lack of resources caused by over-occupied by network congestion and security risks and other issues hindered the normal networks operations. P2P technology holds the vast
6、majority of network bandwidth, how to control the P2P traffic, is that we enjoy the convenience brought by P2P at the same time must be considered a problem. Therefore, the effective realization of P2P traffic identification and control has become an urgent problem. It is against this background pap
7、er, for the characteristics of P2P traffic carried out research work. Paper mainly contains the following: 1, for P2P technology is studied. Respectively, P2P technical definition, P2P technology, four kinds of network topology model, P2P technical characteristics, P2P key technologies, P2P-related
8、protocols and applications are analyzed. 2, a detailed analysis of the P2P flow problems in identifying, focusing on study and compare the current existence of several P2P stream recognition programs works, as well as its recognition in the process of P2P flow characteristics and problems of flow co
9、ntrol is also introduced several technology and management strategies. 3, flow testing programs for existing P2P shortcomings, presents an improved side after the Comprehensive Test Case, in the new program features the use of traffic detection and integrated deep packet inspection and other testing
10、 methods identified. The program to overcome the current flow of several P2P identify options, effectively improved the recognition rate of the P2P flow. 4, the paper presents a program designed based on a P2P traffic identification and management system, the system can be 校 园 网 问 题 解 决 方 案 河南大学 信息系
