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。
As IP broadband technology evolves and the end-user experience matures, the driving force behind the development of the entire Internet has been transformed by the services designed by early Internet operators and technology vendors into the ultimate target audience. In response to the trend of end-user demand, the network real-time requirements of the Internet and the rapid growth of multimedia applications are increasing. More and more traditional telecommunication network services such as video and voice are migrated to the Internet based on an IP-based bearer network. At the same time, however, VoIP (in short, digitizing analog voice signals and transmitting them in real time over IP data networks in the form of data packets) services and P2P (P2P is short for English Peer-to-Peer, also known as “Point to point ”) Download Rapid warming, resulting in Internet data transmission quality can not be guaranteed, the business can not be predicted, the Internet’s control mechanisms and behavioral characteristics are also increasingly complex. The purpose of this paper is to better solve the bottleneck of edge gateway congestion and improve TCP / UDP transmission performance so as to provide better service quality for key services.
