【摘要】：随着网络规模的持续扩大，网络结构也日趋复杂，人们对网络服务的要求越来越高。同时，加快落实IPv6下一代互联网产业建设，推进新型网络体系架构及技术研发工作成为当务之急。传统的网络监控系统很难满足企业对IPv6网络的管理，为了更好地服务客户，企业需要及时了解IPv6网络中承载的业务，及时掌握网络流量特征，在这种背景下，IPv6NetStream技术应运而生。本文是结合自己所参与的基于IPv6NetStream技术的网络流监控系统项目的开发，研究了国内外网络流监控系统的发展现状，阐述了IPv6NetStream的相关基本概念、原理和方法，介绍了网络流监控的相关技术；分析了IPv6NetStream系统业务和性能需求，并对系统的数据和过程进行建模；给出了系统的应用架构设计，设计了系统多个不同功能模块的实现方法；实现了对数据报文的统计、老化、聚合、输出以及配置管理等功能。基于对IPv6NetStream网络流监控系统的测试结果表明，，该技术能够对网络中的业务流量进行统计和分析，及时了解各种网络应用占用的网络带宽，各种业务消耗的网络资源和网络应用中Top N流量的来源，及时发现网络瓶颈，防范网络病毒的攻击，有效提升了网络管理的质量，达到了预定设计目标。
[Abstract]:With the continuous expansion of the network scale, the network structure is becoming more and more complex, and the demand for network services is becoming higher and higher. At the same time, accelerate the implementation of the next generation of IPv6 Internet industry construction, It is urgent to promote the new network architecture and technology research and development. The traditional network monitoring system is very difficult to meet the management of IPv6 network. In order to better serve customers, enterprises need to understand the business carried in IPv6 network in time. Under this background, IPv6 NetStream technology emerges as the times require. Based on the development of network flow monitoring system based on IPv6NetStream technology, this paper studies the current situation of network flow monitoring system at home and abroad, and expounds the basic concepts, principles and methods of IPv6NetStream. This paper introduces the related technologies of network flow monitoring, analyzes the business and performance requirements of the IPv6NetStream system, and models the data and process of the system, presents the application architecture design of the system, and designs the implementation methods of several different functional modules of the system. The functions of statistics, aging, aggregation, output and configuration management are realized. Based on the test results of IPv6NetStream network flow monitoring system, the results show that the technology can statistics and analyze the traffic in the network, and understand the network bandwidth occupied by various network applications in time. The network resources consumed by all kinds of services and the source of Top N traffic in network application can find the network bottleneck in time, guard against the attack of network virus, effectively improve the quality of network management and reach the predetermined design goal.
