网络性能测试之iperf的安装使用
Iperf 是一个网络性能测试工具。Iperf可以测试TCP和UDP带宽质量。Iperf可以测量最大TCP带宽，具有多种参数和UDP特性。Iperf可以报告带宽，延迟抖动和数据包丢失。
Iperf使用方法与参数说明
参数说明
-s 以server模式启动，eg：iperf -s
-c host以client模式启动，host是server端地址，eg：iperf -c 222.35.11.23
通用参数
-f [k|m|K|M] 分别表示以Kbits, Mbits, KBytes, MBytes显示报告，默认以Mbits为单位,eg:iperf -c 222.35.11.23 -f K
-i sec 以秒为单位显示报告间隔，eg:iperf -c 222.35.11.23 -i 2
-l 缓冲区大小，默认是8KB,eg:iperf -c 222.35.11.23 -l 16
-m 显示tcp最大mtu值
-o 将报告和错误信息输出到文件eg:iperf -c 222.35.11.23 -o c:\iperflog.txt
-p 指定服务器端使用的端口或客户端所连接的端口eg:iperf -s -p 9999;iperf -c 222.35.11.23 -p 9999
-u 使用udp协议
-w 指定TCP窗口大小，默认是8KB
-B 绑定一个主机地址或接口（当主机有多个地址或接口时使用该参数）
-C 兼容旧版本（当server端和client端版本不一样时使用）
-M 设定TCP数据包的最大mtu值
-N 设定TCP不延时
-V 传输ipv6数据包
server专用参数
-D 以服务方式运行ipserf，eg:iperf -s -D
-R 停止iperf服务，针对-D，eg:iperf -s -R
client端专用参数
-d 同时进行双向传输测试
-n 指定传输的字节数，eg:iperf -c 222.35.11.23 -n 100000
-r 单独进行双向传输测试
-t 测试时间，默认10秒,eg:iperf -c 222.35.11.23 -t 5
-F 指定需要传输的文件
-T 指定ttl值
