基于IXP2400的流量控制实现

Traffic control based on IXP2400

网络流量控制(TC)是为了保证网络中不同服务的需要,在确保业务可靠性、时延、时延抖动、吞吐量、包丢失率的前提下,充分利用各调度机制对网络中各种业务流的状态所进行的控制。网络处理器平台提供了高效灵活的处理机制,优化了网络包处理。基于Intel IXP2400的平台,通过对IPv4包头中ToS字段的修改及判断,更好地实现了网络流量控制。

Network Traffic Control （TC） is to satisfy the needs of Different Services in network . With the premise of providing business reliability, delay, delay jitter, throughput, packet loss rate, it takes full use of scheduling mechanism to control the states of all the business flows. Based on the Intel IXP2400 platform, this paper achieved better network traffic control through changing and judging the Type of Service（ToS） field of IPv4 header.
