My BQM - Your thoughts please.


[link to this post]
 
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

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.

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.

still poor showing.

eg. did your adsl show that level of packet loss.

[re: tommy45] [link to this post]
 
Just had my second engineer round now.

He plugged the JDSU unit straight into the main socket and the readings were normal. He then powered up his own Openreach modem and his colleagues noticed that the noise levels had increased. The exact same test was done where the cable come directly into the property and the modem was connected through an extension which was plugged into a different socket. Again when the modem was powered up the person at the Openreach call centre saw the noise on the line straight away.

Openreach now want a specialist engineer and R.E.I.N. tester to come to the property. Just completely bewildered as to where the interference is coming from! Connection is very choppy at the minute, the connection is cutting out every 10-15 mins.

your loss is lower than the OP's but still high, in your case my guess it would seem you got noise between you and the cabinet, you using the same router?

We've already established that the OP has a fault, so the comparison is meaningless.

ADSL2+ modem/router was a 3Com, now it's the OR modem and an Airport Extreme router.

It would be nice to have zero packet loss, but some of us have to live in the real world and <0.1% doesn't matter.

You think it's high, I don't.

Wish I could get back to that rate of packet loss.

I'm surprised the engineer didn't try switching you to a different MSAN in the cabinet while he was there, it would have been worth a try!

I asked if they could do that and then if I could test the service for the next week before they get more people in. They want to check the interference first and then they will try switching the MSAN.

2 hours ago I was getting 1Meg Down and 1.5 Meg up. Now I am getting 25Meg Down and 8 Meg up ..it's all very strange!

I can see from the BQM (which will be "live" until midnight) that the packet loss disappeared abruptly at about 9:15-ish, with no jump in latency like the last time... very odd confused

I know I have just seen that as well, it's very odd. I have had the same electrical equipment on for the last 4 hours just to test out BT's theory. I have a feeling they will eventually find an issue at the cab rather than at my property.

Same here. Something external that can kick up that much interference would likely be taking out the DSL of half the street!

I will show the graphs to the engineers when they come round, there have been three huge bands of packet loss over the last 3 days, all after 4pm..hopefully they will at least take that into consideration.

Very interesting, if that were the case I would expect other properties who are connected to the same cab to be seeing similar issues? May point that out to them.

No fttc is powered by a proper mains electrical feed to avoid any interference or spikes from street lighting. The cabs even have telemetry lines on the electric supply so OR have planned this aspect properly.

to be honest yours looks acceptable outside that bloodbath period, only small red dots which is what I was trying to say s normal. are you also on idnet or diff isp? as that graph looks much better than the others when ignoring the 12pm to 9pm. clearly some kind of fault condition in those hours.

I am with Aquiss at the moment, the graph is looking ok now, however I have just ran a BT speedtest this morning and have noticed that my upload has now dropped to around 1.5Meg. I have never had a problem with my upload speed before. It's all very strange.

Here is a link of the live graph:

Another IDNet BQM graph.

All the five non-murmuring spikes are speed tests, either tbb or BT. The small bunch of packet drop just after midnight is the start of off-peak when the heavy downloaders hit the system. It was the same 24 hours earlier.

Just reset my BT Open reach modem now and my I.P profile(down) has shot up to 38717Kbps and reported download speeds of 28.82Mb/s which sounds about right as it is a peak period.

However my upload speeds have gone down to 1.5Meg now which is strange!

BT are coming again for the third time and have claimed to have found the issue as being a problem with the 'Access Network'.

Packet loss yesterday was the worst it has ever been, from 10am - 10pm the connection was all over the place.
