用Java进行网速测试
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:
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
-l size Send buffer size
-w timeout Timeout in milliseconds to wait ``for
each reply.
-n count Number of echo requests to send.
