基于FPGA的软件定义流量发生器

Implementation of software defined traffic generator based on FPGA

流量发生器广泛地应用于各种网络环境中,对于交换机、路由器、协议控制器芯片以及网络本身的测试与分析有着重要的作用。针对现有流量发生器种类较少、配置灵活度不高的问题,提出了一种基于FPGA(field programmable gate array)的软件定义流量发生器,实现灵活配置每个端口的数据分组的协议类型、数量、长度、间隔等,具有高速性、灵活性和可扩展性。

Traffic generator is widely used in various network environments.It plays an important role in testing and analysing the performance of switches,routers,protocol controller chips and network itself.To address the problem that not much type and less flexible of exiting traffic generator,a software defined traffic generator based on FPGA was described.It realizes the configuration of packet protocol type,packet quantity,packet length,packet interval of each port through software,Such a structure has the character of high speed,flexible and extensible.
