【摘要】 流量分析技术是网络管理的重要组成部分,为网络管理提供数据支撑。描述了基于流的IP流导出标准IPFIX(IP Flow Information eXport)的工作原理,分析了IPFIX流形成与处理的整个过程,并对流量分析系统结构进行研究设计。针对分析器可能产生的性能瓶颈问题,提出两点解决方案,并描述了收集器负载均衡的实现方法。更多还原

【Abstract】 The technology of flow analysis plays an important part in network management,and it provides relational data to support network management.The flow analysis which based on flow technology is used widely because of its advantages.This thesis describes the operational principle of IPFIX,which is an IP flow export standard based on flow technology.The procedure of flow generation and process are illustrated,and the architecture of flow analysis system is researched in this thesis.Two solutions are provided to avoid the bottleneck of the analyzer performances,and load balance methods of the collectors are implemented in this thesis.更多还原
