There is a way to measure latency network in java

Question

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?

Anyway, thank you

Answer 1

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

This is by definition, latency

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

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;
         }
