(转)如何用ping 命令简单测试网速

命令格式：

ping ip地址 -l 字节数

注：上面的命令中 l 是字母l,不是数字1

网速等于≈(发送的字节数/返回的时间[毫秒])K字节

以上计算的结果速为字节(byte)，不是我们通常说的位(bps)

如：

C:/Documents and Settings/Administrator>ping 202.101.224.68 -l 1000

Pinging 202.101.224.68 with 1000 bytes of data:

Reply from 202.101.224.68: bytes=1000 time=38ms TTL=251
Reply from 202.101.224.68: bytes=1000 time=38ms TTL=251

Ping statistics for 202.101.224.68:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 38ms, Maximum = 38ms, Average = 38ms

根据上述发送及返回的信息可以简单得出到地址202.101.224.68的网速为：

网速等于≈(发送的字节数/返回的时间[毫秒])K字节
        ≈1000/38K字节
        ≈26.32K字节
