摘　　要：设计并实现了一种基于DPI技术的带宽管理系统,系统的数据流捕获模块和协议识别模块采用了Libpcap函数库和AC算法等内容构建而成。在流量整形方面则提出了HTB_resv流量整形算法和动态带宽调整算法,以此来解决常见的带宽管理系统存在的协议识别率较低和因带宽竞争导致流量整形策略失效的问题。A bandwidth management system based on DPI technology is designed and implemented.The data stream capture module and protocol identification module of the system are constructed by using Libpcap function library and AC algorithm.In the aspect of traffic shaping,the HTB_resv traffic shaping algorithm and the dynamic bandwidth adjustment algorithm are proposed to solve the problem that the bandwidth recognition rate of the common bandwidth management system is low and the traffic shaping policy is invalid due to bandwidth competition.
