I am trying to understand PingPlotter and I'll pose this question to who ever....
As I understand this (PingPlotter) it will tell you whare a particular problem may be BUT you can't do anything to actually correct it yourself. Am I correct in assuming that? I think I read that if you see a problem you may want to contact your service provider and see if they can correct the problem. If that's the case, it would be very difficult. I use Comcast as my high speed Internet provider as well as my TV and phone system. I can't imagine they would re-route for a single customer....? Maybe I'm not understanding this correctly. If someone could explain exactly what PingPlotter does, I'd appreciate it. 73 Jerry - N1TKO |

Well, if you find out that the lagging is caused by a faulty core-router somewhere along the line, chances are slim to be able to fix that. But router problems usually fixes themselves. PingPlotter sends small nibbles of data traffic (ping) to all routers along the way between two IP numbers. Each hop (router) is probed and the ping times respectively packet loss is measured. If a router suffer from high load or so called "route flaps", it may produce a high packet loss. This is normally not a problem for TCP traffic as the protocol (TCP) has built in tracking so that all packets reach the destination and in correct order. But since packets are lost, there will be a "resend" scenario that will consume some performance. Yes, the packets arrive, but perheps a little late due to these "lossy" routers. In this way you can understand whats going on when audio is lagging in HamSphere. There is a PingPlotter FAQ that tells you quite a bit. I doubt that you will get any attention from a service provider if you send them PingPlotter dumps. Of course, if you have a constant lossy/lagging scenario it may be worth looking at and perheps they will react. But usually these problems come and go and it is a part of the Internets structure. Another important thing is to compare the "routes" the packets take from one day to another. Since Internet is constantly reshaping itself, you may have good and bad days, depending on the load, routers, peering agreements etc. 73 Kelly |

Thanks Kelly
I was really puzzled regarding that.... I will read the FAQ's on PingPlotter although you have answered my basic question. Thanks for the time!! 73 Jerry N1TKO |
