摘　　要：流量发生器是一种网络测试工具,可以用于测试特定场景下的网络性能等。现有的流量发生器多基于软件实现,且多数流量发生器仅支持单一协议的流量产生,不够灵活。设计并实现了一种基于现场可编程门阵列(Field Programmable Gate Array,FPGA)的支持Eth、FC、SRIO、PCIe等多种协议的软件定义流量发生器,拥有更灵活的配置选项和更加优良的性能,并且能够支持任意输出数据流大小的精确可控,同时方便实现了多种数据流的灵活混合。Traffic generator is a network testing tool that can be used to test network performance in specific scenarios,etc.Existing traffic generators are mostly software-based and support only singleprotocol traffic generation,which is not flexible enough.A software-defined traffic generator based on field programmable gate array(FPGA)has been designed and implemented to support multiple protocols such as Eth,FC,SRIO,PCle,etc.It offers more flexible configuration options and better performance,and can support precise and controllable output data stream size,which facilitates the flexible mixing of multiple data streams.
