Ping and the Link speed

We have a point to point link IPLC Line between two locations and we upgraded from 512k to 1Mb and to 2Mb but the pinging time to between one location to other always remains the same. It was 260Msec when the link speed was 512k and then to 1Mb and now with 2Mb also it is the same. Is the pinging time does not depend on the link speed? What are the parameters should be used for reachability between any location either point to point or general internet servers.

Thanks in Advance

Re: Ping and the Link speed

Your bandwidth has been upgraded but not delay. They are different.

Both electrons and photons have maximum attainable speeds through different medium. You will see ping timings decrease, if e.g you upgrade your coppper to fiber or shorten the distance between two points. You will see ping times increase with the distance. Other factors that may change ping returns could be congestions, nodal processing delays, overloaded servers etc.

Hope this helps.

Hello Rais,

that is cool stuff you are writing down here, I will save that explanation of ping delay times for future use !

Re: Ping and the Link speed

Really a cool answer from Rais.

Also when you upgrade from 512K to 1Mb link, u r trying to push double the data per second.Its like moving from 32 bit processor to 64 bit processor PC.

Re: Ping and the Link speed

Well, you would need quite large distances for a change in length to make much difference.

For a link up to a few kilometers the speed of electrons is negliable.

And of course bandwidth matters. If you, for some dumb reason, would send a ping packet of 1500 bytes over a connection it would take longer time on a 56k modem than on a T1. If this is not crystal clear to you, please say so and I will give you mathematical evidence for it.

Secondly, most of the delays you see on connection is related to equipment itself and its parameters.

I have lowered ping times on a ADSL connection from 30 ms to about 6ms using only software control.

With a 2 Mbit connection you should NOT have 260ms ping provided you are pinging the closest node on the other side. If you for example is pinging www.google.com or similar, don't be suprised to see ping times of over 200 ms.

Hope it makes sense ;)
