Data transfer time

Question

i would like to know how much time is needed to send a packet of 12 octets with the TCP IP protocol through a Socket.
Can you explain me how you know that and where can i found more information?
thanx thanx

Answer 1

You can use System.getCurrentTimeMillis() before you send the packet and then do a System.getCurrentTimeMillis() after you send it. The difference will give you the time in milli seconds. Remember, the function returns a long.
//Create the socket
//Form the packet
long startTime, finishTime;
startTime=System.getCurrentTimeMillis();
socket.send(packet);
finishTime=System.getCurrentTimeMillis();
double time = (double)(finishTime-startTime);
But, the time depends on:
1/ Hardware
2/ OS
