硬件：XENA Valkyrie 或 Vantage主机，测试板卡不限，本方法适用于其100M~400G所有速率端口
环境配置：Python 3
实现功能：
1.控制流量仪进行流量测试，预定配置的流量发送，报文统计，丢包率，延迟等信息的统计
2.单个Python脚本配合不同的JSON对象文件，来实现不同端口数量，不同拓扑模型下的流量测试
3.在发包测试前及运行过程中都对发包端口的链路状态进行监控100M/1G/2.5G/5G/10G
4.嵌入ARP探测，获取DUT的MAC信息，并记录在测试日志中
5.统计端口流量的Tx,Rx信息，丢包率，延迟信息
设计思路：main文件控制主流程，嵌入Statistics模块进行数据统计，CreateClass模块进行命令预定义
运行效果：
