基于NETFLOW与SNMP的园区网流量监控系统

随着园区网不断扩展，IP网络承载的数据流量越来越大，业务也越来越复杂。加上病毒泛滥、黑客攻击等因素，更加重了网络管理的负担。传统网络管理工具都是基于SNMP协议的，但SNMP只适合于简单的流量监控与设备管理，缺乏流量分析功能，当需要对流量进行分析或依据流量分析的结果实施网络管理时，传统工具就力不从心了。NETFLOW是一种可用于流量分析的协议，将其与SNMP协议结合使用，可有效弥补SNMP的不足，在充分发挥NETFLOW流量分析与SNMP流量监控与设备管理性能基础上建立的监控系统，可有效提高园区网管理的质量与效率。

Monitoring System on Campus Network Based on NETFLOW and SNMP

With the rapid development of the campus network,IP network carries more and more pressure due to the growth of data traffic flow.The service is also more and more complex.Virus,hacker attack,make network management burden heavier.The traditional network management tool is based on the SNMP protocol.But SNMP only suits in the simple current capacity monitoring and the network devicemanagement,lacks the current capacity analysis function. When needs to carry on the analysis or the basis current capacity analysis result implementation network management to the current capacity,the traditional tool lacked the ability to do what one would like.NETFLOW is available in the current capacity analysis,it with SNMP protocol union use,can makes up SNMP effectively the insufficiency.Based on SNMP and NETFLOW establishment supervisory system,can effectively improve the quality and the efficiency which the campus network manages.
