怎么ping网速?

　　Ping 在Windows系下是自带的一个可执行命令。利用它可以检查网络是否能够连通，用好它可以很好地帮助我们分析判定网络故障。应用格式：Ping IP地址。该命令还可以加许多参数使用，具体是键入Ping按回车即可看到详细说明。

下面，本文就教你用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

　　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：b3hN_M[9I|&!s

　　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

附：ping命令帮助说明

　　C:\Documents and Settings\Administrator>ping /?

　　Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS]

　　[-r count] [-s count] [[-j host-list] | [-k host-list]]

　　[-w timeout] [-R] [-S srcaddr] [-4] [-6] target_name

　　Options:

　　-t Ping the specified host until stopped.

　　To see statistics and continue - type Control-Break;

　　To stop - type Control-C.

　　-a Resolve addresses to hostnames.

　　-n count Number of echo requests to send.

　　-l size Send buffer size.

　　-f Set Don''''t Fragment flag in packet (IPv4-only).

　　-i TTL Time To Live.

　　-v TOS Type Of Service (IPv4-only).

　　-r count Record route for count hops (IPv4-only).

　　-s count Timestamp for count hops (IPv4-only).

　　-j host-list Loose source route along host-list (IPv4-only).

　　-k host-list Strict source route along host-list (IPv4-only).

　　-w timeout Timeout in milliseconds to wait for each reply.

　　-R Trace round-trip path (IPv6-only).

　　-S srcaddr Source address to use (IPv6-only).

　　-4 Force using IPv4.

　　-6 Force using IPv6.
