[网络协议]iperf测UDP和TCP丢包率及带宽

iperf

iperf3 （安装包是：iperf-master）安装遇到error while loading shared libraries:libiperf.so.0
解决方法：在正常编译以后运行ldconfig
安装软件包的方法(参考REDMINE)：在顶层目录下：
./configure
make
make install

yqq@ubuntu18:~/Tool/iperf-master$ iperf3 -s
iperf3: error while loading shared libraries: libiperf.so.0: cannot open shared object file: No such file or directory
yqq@ubuntu18:~/Tool/iperf-master$ sudo ldconfig
yqq@ubuntu18:~/Tool/iperf-master$ iperf3 -s      
//tcp和udp服务器端用iperf3的话都是这个命令，如果是udp，在客户端加上-u即可
//如果是iperf，tcp和udp在服务器端加-u，tcp和udp的客户端命令相同
Server listening on 5201 (test #1)

安装

方法1：sudo apt-get install iperf
方法2：下载iperf的源码包( 在板子上使用二进制文件时，可将源码直接拷贝到板子上 ./configure make)

测试

无论是tcp还是udp方式测试，都要一端运行服务器模式，另一端运行客户端模式，另外如果打开了iptables,要打开tcp 5001端口，当然也可以指定端口

tcp方式

服务器端：iperf -s
客户端： iperf -c SERVERIP -t 60 -i 1 -P 5

udp方式

服务器端：iperf -u -s //iperf3服务端不支持-u选项
客户端： iperf -c SERVERIP -t 60 -i 1 -b 100M

共用的指令

-f            --格式[k|m|K|M]分别表示Kbits，Mbits，Kbits，KBytes，MBytes显示报告，默认是Mbits
-i            --以秒为单位统计带宽值
-l            --读写缓冲区的大小，默认是8kb
-m            --显示最大的TCP数据段大小(MTU-TCP/IP header)
-o            --将报告和错误信息输出到文件
-p            --指定服务器和客户端连接的端口
-w            --指定TCP窗口的大小，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和client端版本不一样时使用）
-M            --指定TCP 数据包的最大MTU值
-N            --设定TCP不延时
-V            --传递ipv6数据包 
适用于server
-s            --服务器
-U            --单线程UDP模式下运行
-D            --以守护进程模式运行 
适用于client
-b            --指定客户端通过udp协议发送信息的带宽，默认为1Mbit/s
-c            --客户端 
-d            --同时进行双向传输测试
-n            --指定传输的字节数
-r            --单独进行双向传输测试
-t            --指定iperf测试时间，默认10秒
-F            --指定需要传输的文件
-I            --从标准输入(stdin)中读取要传输的数据
-L            --指定一个端口，服务器将利用这个端口与客户端相连
-P            --客户端到服务器的连接数，默认为1
-T            --ttl值
-u            --使用udp协议

# iperf -s -u               //此为iperf，不是iperf3，如果是iperf3 则如果是测试UDP，则在客户端加上-u，服务器不需要-u
