Will this high latency effect our requests sent over this backhaul.  For instance we use VOIP over our network and are experiencing dropouts / lost packets.  However when we ping to the same destination we are seeing only 30ms which we would normally expect.

What is the difference between Traceroute & ping?  

Many Thanks

traceroute shows you the whole route an ip packet takes to get to it's destination.  that way you can see if you have some failing hardware somewhere in the middle.

ping sends a request to the host and tells you how long it took to get a response.

Here is one that you might not know of...try pathping

This could simply be misrepresentation of the latency from that particular hop.  Unless you run the device that is showing the high latency in a trace and know otherwise, it may be a false positive.  Consider that the icmp echo to that particular hop is separate than the traffic to your destination, and that as long as your ping is low (30ms is good), your traffic to your actual destination is sound.

For trace/ping anyways.

Thank you for you comments, our backhaul providers are suggesting similar - that Traceroute requests from their core router are not high priority and so this is why we are seeing long response times. That it could be down to high levels of traffic, thus the wait for traceroute response.  We can see how this is plausable but we know that we are no way near maxing out our backhaul we would expect much quicker response times to traceroute requests even if not a priority. Would you agree?  For example Traceroute response times have been as high as 17seconds!

We have run similar tests from a seperate independant Virgin Broadband Line (Different Backhaul) & do not see these issues.

We have tried Pathping & see only a few latency results but no where near as long as a Traceroute latency.

Furthermore our line quality is now beeing reported as a B grade using pingtest.net whereas we have always been A grade.  

Any further tools or suggestions welcome.

Further suggestions to our responses & follow-up  would have moved towards Grade A.
