My BQM - Your thoughts please.

Hi All,

Please can someone analyse my BQM, I am intrigued to find out what has caused the huge amount of packet loss last night. Has anyone else had a similar problem before?

Thanks




My Broadband Ping

That amount of total packet loss is the connection dropping repeatedly. You can also see quite distinctly where your IP Profile changes and the level of interleaving increases.

It amuses me to see that my 63db loss ADSL connection has a lower minimum latency (at 20 msec) and I don't get the continual low level of packet loss that you appear to suffer from.

Could be interference from a property nearby,R.E.I.N. could also be cross talk at the dslam exchange or cab,

Something has gone horribly wrong somewhere... apart from the problem last night that caused the repeated loss of connection, resulting in a rise in latency (probably a hike in target SNRM and interleave being switched on) there's an odd-looking periodic blip all the way from midnight to about 8am, with another latency rise at about 4:30pm, when your packet loss largely clears up.

I think you need to do some investigating... and maybe a call to CS to see if they can tell anything from their end.

Yes something is definitely not right, already had my profile reset twice, two period of disconnections and my ping has shot up from 20ms to 35-40ms now. Profile has dropped from 38970 to 27365. BT Openreach are investigating at the moment.

hmm yet another FTTC graph with packet loss.

You seem obsessed with packet loss... Don't forget that the only traffic the BQM shows is ping packets between tbb and your router- ie low priority stuff. No router is going to care if it throws away a ping.

I am obsessed as packet loss is a killer, my dodgy adsl line has specks of red on a normal day, these graphs look a mess. If I was a customer with that on my graph I would be complaining every day until its fixed. I would be very concerned with ping packetloss, as I dont expect my router to be at 100% utilisation and believe me that kind of packet loss is not normal. Although granted it may be a transit issue between tbb and idnet causing it rather than everyone having a lossy fttc line.

Incidently icmp is usually lower priority but not UDP.
