客户端命令行：iperf -u -c 2xx.1xx.1xx.1xx -p 20001 -l 1380 -B 172.16.28.173 -t 10 -i 1 -b 1800K

e.g.

iperf -u -c 10.12.23.47 -p 8080 -l 1380 -B 10.12.32.45 -t 10 -i 1 -b 200M

参数解释：

1) 测试对端是10.12.23.47

2) 测试对端的端口是8080

3) 数据包大小是1380个字节

4) 绑定本地网卡10.12.32.45

5) 测试持续10秒钟

6) 每隔1秒钟打印一次信息

7) 最大发送带宽200M

服务器命令行：iperf.exe -s -u -i 1 -p 8080 -l 1380

/* 
* Bandwidth Test with iperf
*
* Client Command Line:
* 1) a packet is of 1380 bytes length.
* 2) bind to a local interface 172.16.28.173
* 3) Test for 10 seconds, and every 1 second, print a recode.
* 4) limit the send Bandwidth to 1800K.
* iperf -u -c 2xx.1xx.1xx.1xx -p 20001 -l 1380 -t 10 -B 172.16.28.173  -t 10 -i 1 -b 1800K
*
* Test Sample I.
