随着网络规模的增大和网络结构的复杂化，计算机网络中的设备根据不同的应用需求，数量和种类也非常繁多，网络管理的难度也随之加大，其中一个重要问题就是对网络流量进行分析、统计以及控制。通过SNMP协议对MIB实时采集，可以实现网络流量监测，当网络核心节点端口出现流量异常的情况下，向防火墙发送控制指令，实现针对不同服务优先级别的网络应用进行流量控制，可以有效保障重要的网络应用需求在高峰时段的速率，并且可以实现在网络使用的空闲时段满足低优先级的网络应用。

With the increase of the network size and the complication of the network structure,according to various application demand for the equipment of computer network,the amount and type are very diverse,network management becomes more and more difficult. One of the key problems is analysis,statistics and control of network flow. Through SNMP finish real-time acquisition for MIB,monitor the net-work flow. When an exception occurs in the core node,management station sends the control instruction to firewall. According to the dif-ferent priority of application,can realize control of the network flow to guarantee the rate for important network application demand dur-ing peak hours,and meet the network application with low-level in free time of network.
