IP网络流量控制技术的应用及发展

Application and Development of IP Network Traffic Control Technology

随着IP宽带技术的发展以及最终用户体验的成熟,整个Internet发展驱动力已由早期的互联网运营商和技术厂商所设计提供的服务,转换为最终目标用户的驱动力。顺应最终用户的需求趋势,Internet的网络实时性要求和多媒体应用快速增长,越来越多的视频、语音等传统的电信网服务迁移到以IP为基础承载网的Internet。然而同时,VoIP(VoIP简而言之就是将模拟声音讯号数字化,以数据封包的形式在IP数据网络上做实时传递)业务与P2P(P2P是英文Peer-to-Peer的简称,又被称为"点对点")下载急剧升温,导致Internet数据传送质量无法保障,业务无法预测,互联网的控制机制和行为特征也日趋复杂。该论文研究的目的是为了较好解决边缘网关拥塞瓶颈的问题,提高TCP/UDP传输性能,从而为关键业务提供更好的服务质量。

With the development of IP broadband technology as well as the maturity of the end-user experience, the driving force of the whole development of Internet has provided the early service designed by Internet operators and technology vendors and transfers as the driving force of the ultimate goal user. Adapting to the needs of the end user trends, the Internet network real-time requirements and the rapid growth of multimedia applications, more and more video, voice and other traditional telecommunications network service migrate to the IP-based bearing network Internet. However, at the same time, VoIP （VoIP in short is the analog sound signal digitiza- tion and real-time delivery） business and P2P （ P2P is the English short form of Peer-to-Peer for the type of data packets in the IP data network, also known as the Point-to-Point） downloads rapidly warming, leads to that the Internet data transmission quality cannot be guaranteed, the business cannot be predicted and the control mechanisms and behavioral characteristics of Internet are becoming in- creasingly complex. The purpose of the thesis is to better solve the bottleneck problem of edge gateway congestion, increase the TCP / UDP transmission performance, thus provide a better quality of service for business-critical.
