有一种方法可以在java中测量延迟网络 [英] There is a way to measure latency network in java

问题描述

我在一个简单的程序中工作，一开始我将在所有 MAN 主机上 ping 以验证所有主机是否在线(完整)，但我想实现某种方法来测量主机之间的延迟.有没有办法做到这一点?有什么提示吗?

I'm working in a simple program, for beginning i will ping in all MAN hosts to verify if all hosts are online (complete) but i want implement some way that measure latency between hosts. Is there any way to do that? Any tips?

无论如何，谢谢

推荐答案

您可以为 ping 和 pong 打包保留一个时间戳，并简单地计算两者之间的差异两个.

You can keep a timestamp for the ping and the pong packed and simply compute the difference between the two.

这是根据定义，延迟

您可以多次重复该过程以计算其他指标，例如抖动.

You can repeat the process more that one time to compute other metric, such as the jitter.

以下简单的事情应该可以达到目的.

Something simple as the following should serve the purpose.

while (sentPacket < MAX_PACK_NUM) {
            // Timestamp in ms when we send it
            Date now = new Date();
            long msSend = now.getTime();
             ....
            //send ping
            socket.send(ping);
            //receive ping
            socket.receive(response);
            now = new Date();
            long msReceived = now.getTime();
            // Print the packet and the delay
            long latency= msReceived - msSend;
            ++sentPacket;
         }
