Propagation Delay Calculator??????????

[mysqlvirgin]

Hi, i want to create a very simple calculator to calculate the propagation delay of a network from the distance the signal has to travel. I also want to calculate the transmission time from the message size and data rate. Plus calculate the total delay by adding the progagation delay and the transmission time.

I have no idea on how to do this using java script? Any idea's?

Many thanks

I did not exactly grab what you wanted to do... but this may be of some help...

<script type='text/javascript'>
var StartTime, StopTime
function launchclock(){
StartTime = new Date();
}
function howlongwuzzat(){
StopTime = new Date();
alert(StopTime - StartTime + ' millisecondes');
}
</script>

initiate clock with launchclock()
lauch action you want to test
retrive time with howlongwuzzat()
