基于SNMP协议的网络流量侦测系统设计及实现

Designing and implement of net flow detection system based on SNMP

介绍网络管理的协议标准,在SNMP协议的基础上,设计并实现了一种不同厂商网络交换设备的流量侦测系统———NSDFD,该系统能够及时发现网络中的拥塞位置和攻击源主机.

The paper introduces the protocol standard of network management briefly. On thebasis of SNMP, we design and realize a net flow detection system- NSDFD, which can be used for switch devices of various manufacturers. The congestion location of the network and the malicious host with NSDFD, can be detected.
