TBB graph latency increase on IPv6

brueton — Wed, 29 Jan 2014 08:50:56 GMT

Did anybody else see the latency increase between approx. 9pm & 10pm last night (Tue 28 Jan 2014).
It appears to be on IPv6 only.
Router is Billion 7800N.

Never mind the latency - what about that packet loss all day!

Any other IPv6 customers see a similar hump on their graphs?

No - not to the same extent - but my connection was practically idle between 7pm and 10 pm.

Not just last night, seems to happen most nights, some are worse than others.

What on earth is it with the packet loss on your connection? That's so bad you ought to be raising a fault (unless it's something you are doing).

Re: TBB graph latency increase on IPv6

I have raised a fault, ticket 79943732. Waiting for an update which I fear is going to be arranging for an engineer to visit my house when the problem is most likely at the exchange.
Most recent update was on Monday 27 Jan

I am sorry to see that you are experiencing a speed fault.
I have raised this issue with our suppliers.
They have a standard lead time of 48-72 hours to provide a response however we will check for updates sooner and contact you as soon as one is available.
I apologise for any inconvenience caused.

It is not just my connection, a neighbour a couple of doors along, also with Plusnet, is getting the same packet loss.

Do you know anyone using an ISP other than Plusnet (but not LLU) on your exchange? If so are they seeing the same issue?

Have not found anybody else. Everyone I have asked is either Sky, Talktalk or VM cable.

No BT users? I bet if you look at the wireless networks available there's going to be a homehub near you showing up!

One of the "downsides" of living at the end of the lane in a semi-rural area. Not many wireless networks or neighbours.
Just having a look now and can see one VM and three Sky wireless networks.
Probably best if any further discussion on the packet loss is in the topic I opened for that purpose. http://community.plus.net/forum/index.php/topic,122504.0.html
I opened this topic to highlight the difference in latency between IPv4 and IPv6 I am observing at certain times of day. I guess that if there is an exchange fault it might be the cause of both the packet loss & difference in latency.

If one of the mods sees this Would it be possible to move the packet loss discussion to the other thread?

I had the same "bump" - some light web browsing during most of that time:

@AndyH
Did you see a hump on other nights?
7 Jan 2014 seemed to be quite bad for me. There was no use at all of my connection that day, house was not occupied.

7 Jan was not so bad for me

Not sure what I was doing then, but doesn't look like much

Re: TBB graph latency increase on IPv6

Kelly — Thu, 30 Jan 2014 08:55:05 GMT

We suspect the hump is a side effect of lack of IPv6 awareness of the DPI platform at the minute. We need to enable it, the action of which is queued with our ops guys

Re: TBB graph latency increase on IPv6

Many thanks for the update. If only the packet loss in the evenings was as easy to resolve.

It looks like congestion as it increases significantly around the evening peak time window, and reduces to next to nothing during the quietest periods 2am till 6/7am that's what shout out to me re the packet loss

Re: TBB graph latency increase on IPv6

Kelly — Fri, 31 Jan 2014 14:51:10 GMT

I believe it's the same problem we explained before about peak time latency humps and titanium traffic. Will go when we enable DPI on the IPv6 traffic.
