java - 显示我的带宽连接

Question

我需要每X次在我的java框架上显示我的带宽，但我不知道该怎么做，ping只给我可达性而不是带宽......我需要“下载”一些东西来获得速度但我不知道如何...谢谢!

Answer 1

ping 为您提供足够的详细信息来计算带宽

对于下面的 ping 命令

> ping google.com

输出:

Reply from 216.58.197.46: bytes=32 time=26ms TTL=56
Reply from 216.58.197.46: bytes=32 time=25ms TTL=56
Reply from 216.58.197.46: bytes=32 time=26ms TTL=56
Reply from 216.58.197.46: bytes=32 time=25ms TTL=56

Ping statistics for 216.58.197.46:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 25ms, Maximum = 26ms, Average = 25ms

传输 32 字节数据的平均时间为 25ms

因此

带宽 = (32/25) 字节/毫秒 = ( 32*8/0.025 ) bps = 10240 bps = 10240/1024 kbps = 10 kbps

希望这对您有用。
