摘　　要：路由器是接入网络的关键设备,为了防止网络流量过大而造成网络拥塞的状况,设计了一种在路由器上的网络流量控制系统。DD-WRT是一种开源的路由器固件,对DD-WRT重新定制开发,可以实现用户自己想要的一些功能。介绍了一种基于DD-WRT实现的网络流量统计和控制系统,介绍了系统捕包、流量统计和流量控制的一般流程,同时着重介绍了针对网络应用的流量统计和控制方法。系统采用嵌入式Linux编程,实现了在开源路由器中对网络流量进行控制的功能,并有效地防止了网络拥塞。Router is the key equipment to access network,in order to prevent excessive network flow and network congestion,a network traffic control system on the router has been designed.DD-WRT is an open source firmware of router,you can re-develop it,and you can achieve some of the features you want.Present a network traffic statistics and control system based on DD-WRT,and describe the general flow of the sniffing,the statistics and the control of the system,at the same time highlight the traffic statistics and control methods for network applications. The system is programmed by embedded Linux,and it achieves the network traffic control functions in the open-source router,effectively prevent network congestion.
