Ping increase


[link to this post]
 
On the 29 Nov my Sky latency (Samknows box), went from 14-16ms to 29-31ms and has stayed there ever since. I have spoken to Sky on several occasions who have said, there is nothing they can do, as they have no access to systems that can investigate this. It appears to be a widespread problem (going by alternative forum posts) but the Sky "techies" seem to know nothing about it and cannot help. I know it may not sound like much of an increase but being a sad old gamer I like to have a nice low ping.

Ive had Sky fibre since the 3rd week of Oct when they mistakenly put me on the 40/2 package and this took nearly a month to sort out. It turned out the only people who could fix it was BT, who finally sorted it out for me a month after ordering. Any possibility that BT could be responsible for latency increase and Sky have their hands tied in sorting it out?

The link between you and the exchange is Openreach, their GEA product. It is handed over there to Sky via ethernet and it's Sky's baby from then on.

It could be the Openreach DLM in the cabinet that has put interleaving on. Have you also lost any speed? (Probably not if you get over 70Mbps, but if less than that you might have lost about 8%).

It could be crosstalk as more people near you have been conencted to fibre. It could be Sky getting more heavily loaded at that exchnage.

Not a lot to be done I'm afraid.

[re: RobertoS] [link to this post]
 
Thanks for the reply RobertoS.
It does seem a bit strange, that other exchanges all over the country experienced this increase and Sky seem to know nothing about it.
Going back to my 40/2 problem. When Sky could not sort it, it was eventually passed on to a BT person in Leeds who called me and talked through her process of checking my line and changing the profile there and then. What took Sky nearly a month to try and rectify took BT a few minutes to actually fix it.
Just how much influence does BT have on other companies fibre, it seems to go further than just the exchange. If this is the case.
In regards to crosstalk, can that actually be blamed for such a sudden increase in latency, it wasnt a gradual increase it happened immediately.

29th November is a touch early, but it could also be that annual bugbear- interference from cheapo Christmas lights.

In which case the DLM might relent some time into the New Year and take the interleaving off.

I live in a pretty quiet village connected to a cab 350ms away. On the 29th of Nov there were no Christmas lights up in my small street, with no obvious sign of any between my house and the cab, (near to the bus stop I use daily for work). Although now, the place is lit up like the preverbial.

Ah well, it was a thought.

My neighbour put up his usual half-megawatt of lights around then, but so far (crossing everything I've got two of that can cross) it hasn't caused any problems. It has in the past, maybe he's bought new ones.

Being passed on to a BT person in this situation is highly unusual. It should have been possible for Sky support to liaise satisfactorily with the appropriate BT department. Almost certainly someone in Openreach. All I can say about that is I'm glad it got sorted for you.

Regarding the general setup, this slightly out of date page might explain a lot to you. Sky Fibre is not true LLU, (I'm assuming you know what that is, but on the same site is a "What is LLU?" page), as that would need them to cable out to the cabinets in the same way as Openreach have done. Billions of squidoodles.

So whereas on LLU they have almost complete control of the line, relying only on Openreach for the physical maintenance of the copper from the exchange, on fibre they basically only control it from their LLU kit in the exchange back to themselves. Although they can request a few performance settings. The 40/2, 40/10 and 80/20 settings are simple Openreach products that they order on your behalf, and the performance settings are simply stability increases, QOS settings, and suchlike.

Interleaving and underlying latency are set automatically within Openreach systems. There seem to be no systems for any ISP to request alterations to those. Further variable latency can of course arise within the Sky backhaul system.

Similar to you but not as dramatic, 24 November, after 18 months or so on fast path, interleaving was applied to my line, latency rose by about 4ms, and I lost 10Mbps downstream. 19:45 on 14 December the latency dropped back toi the original value, but the interleaving and the speed loss it causes remain. No known reasons frown . WIth a bit of luck, in a while it will revert to fast path and give me the speed back.

Not even worth pursuing with my ISP. Or any ISP if it happens to one of their customers. I fear it is the consequence of getting the ludicrously high speeds and allowances we now have compared to the past. It would be just impossible Openreach to keep everyone happily on the highest tight-rope seeing as they can provide small performance decreases that stabilise everything.

I hope that helps explain things. I know it doesn't explain why you have had such a big change.

My top three for fibre - BT, Plusnet and Sky. Though I'm beginning to downgrade BT in my estimation.

I expect Zen are OK. I did my first year with IDNet and had no complaints, but from keeping my eyes open here decided I would risk Plusnet for far less money. Ten months into Plusnet I feel I did the right thing, to the point where I'm about to commit to another 18 months from January 13.

Any chance you could perform a tracert to the BBC? It would inform us of where the latency has its highest jump.

Aside from Interleaving, it could be an increase on Sky's backhaul/core network.

In reply to a post by HiPing:
In regards to crosstalk, can that actually be blamed for such a sudden increase in latency, it wasnt a gradual increase it happened immediately.

A large number of lab experiments on crosstalk have been going on for VDSL2, especially as the boffins develop the vectoring concept that will (hopefully) eradicate the effects.

Those experiments tend to show that each line might suffer from umpteen disturbers, but the effect is not equal - and a few of the disturbers have a much more pronounced effect.

So crosstalk might have been gradually being added to the line, or it might just have been a single "heavy" disturber that got turned on. Perhaps they just happen to have the cable next to yours in the run back to the cabinet.

Either way, once sufficient crosstalk is in place, that causes sufficient errors on the line, DLM intervenes to set one of a number of profiles, which set a speed limit and/or a level of interleaving (which reduces speed too).

So yes: gradual increases in crosstalk eventually lead to a step change in latency.

But not usually that large. We had a line problem, and latency went from 13ms to 20ms (then back again a month after the problem was fixed).

I have 2 nodes available to me when connecting to BT.

I believe one is peterborough which gives me 13ms to bbc.co.uk but has spikes every 4 to 5 packets up to 16-17ms. The other which I am using which I believe goes via birmingham is 17ms to the bbc but is much more stable on the jitter.

My cab is the ECI 128 , which has more space than we have houses in our part of the village (other cabs further down the village). It turned out when BT installed fibre for me I was the first one in the village to get it (21 Oct 12). Must have been a mad rush for fibre after I joined, i should have kept my mouth shut.

Yeah. On first installation, my modem reported a maximum attainable speed of 83Mbps. Now (a year later) it says 78Mbps.

Luckily, we haven't resynced for the last month, so it is still running at 80/20. It won't next time though... frown

That's a good point... Most MSANs are (or should be) dual-parented, so there are 2 different routes back to the core network. And for some the difference is significant.

IIRC each PPP session ends up routed one way or the other, so a disconnect/connect at *router* level could cause a change.

mine dropped 20 very quickly. given the potential 40% or so drop expected from crosstalk I would say a 83 to 78 drop over that period of time is pretty good.

If the 21CN core has been built anything like it was originally planned to be, then yes - that part certainly is. That means the ISP's using WBC and WBMC should automatically get this.

Whether the FTTC cabinet is dual-parented (eg 2 different exchanges), or the head-end OLT is duplicated, or is dual-parented (multiple cable-links?), I don't know.

No interleaving means that either (a) Sky support don't know what they're saying about FTTC, or (b) the change in delay is purely down to delays within Sky's network.

How does your ping alter over the course of a day (or night)?

Ordinarily I'd mention a BQM here (see http://www.thinkbroadband.com/ping) but I don't think Sky has static IP, does it?

Just done a quick ping, and tracert to the Beeb from my BT connection, overall 18ms, tracert showing quite a few more hops than the OP's, one even shows 50+ ms.

I don't get the 'missing' 2nd hop he does, anyone else ?

To the OP, my cab has been live for over two years, and there is around 120 connections running from it, so maybe the issue isn't your nieghbours rush for speed ?

What I find interesting is that it seems to have increased from just less than 20ms to about 25 (hard to tell exactly from a graph) in the early hours of 30/11, then from there back to 20ms, then jumped to about 30ms.
Assuming you didn't go an unplug/reboot the modem at midnight, 2am and 5am, that looks like something has been changing a few times in about 5 hours.
Where geographically are you? You are now getting higher pings than I get from Scotland on ADSL...

[re: HiPing] [link to this post]
 
Interesting discussion generally. I've had FTTC through one of the small ISPs - who prides themselves on not "overselling" their network - for well over 12m at a consistent 16ms minimum latency (and average only just minimally higher except during my own heavy downloading) according to TBBQM monitoring. Average results in the same ball park from Trace Route to Google and JDast auto tester's daily tests at various times which uses BBC for ping testing by default. The only noticeable change was a doubling in the latency (to 16ms) after the first month when interleaving was turned on my connection, which was not unexpected. I use a Fritz!Box modem (which shows the latency as 8ms just to the Cab DSLAM) not the OR varieties though, but in fairness it looked stable on my connection anyway.

Interesting though that other FTTC users on the same ISP have recently (over the last month) started to report the same sort of variances as reported here but not to anything like the same extent. Just wondering though as I'm still on 40/10 (as due to distance from the cab as my attainable rate would struggle to get much higher) do these problems particularly afflict those pushing their connections up to 80/20, or whatever? EDIT: just out of interest looked up the JDast monitoring of pings on my fixed wireless connection - which takes the local loop out of the equation but uses Sky's backhaul network via Easynet - and is in the 12-20ms range consistently to bbc.co.uk.

Actually, if you want to see a high ping try 202.80.32.65 - you are unlikely to get less than 800ms to that smile

In reply to a post by Uilebheist:
What I find interesting is that it seems to have increased from just less than 20ms to about 25 (hard to tell exactly from a graph) in the early hours of 30/11, then from there back to 20ms, then jumped to about 30ms.

Yup - I find the same bits interesting. And the changes early on the 5th.

However, I can tell that they're NOT from a modem resync/reboot. If it were, there would be a visible red spike at each change, rather like the spike at 10:15 on the 30th.

Edit: For example, this is where DLM added interleaving, while this is where DLM removed interleaving.

The changes are going to be down to some re-arrangement going on in the Sky backhaul, or the Sky core network itself.

An average of 43ms worse than Billford, typical. Do you know a short cut?

I think so. Their only link seems to be a satellite link to Australia.
Used to be a popular thing to ask to ping whenever anybody complained about high pings on some of the ISP forums smile

No, I've always had excellent ping times from this address, ever since I first got broadband at 2Mbps.

It drives the gamers up the wall, because I have absolutely zero interest in gaming grin

In reply to a post by RobertoS:
My top three for fibre - BT, Plusnet and Sky. Though I'm beginning to downgrade BT in my estimation.

I expect Zen are OK. I did my first year with IDNet and had no complaints, but from keeping my eyes open here decided I would risk Plusnet for far less money. Ten months into Plusnet I feel I did the right thing, to the point where I'm about to commit to another 18 months from January 13.
I suspect I'll do the same thing. It's been a good service from IDNet but there have been four 'incidents' and getting their support to do anything can be a bit of a trial. I was told for instance that my upstream dropping from 14Mb/s to 11Mb/s was a 'slight' change and hardly worth complaining about. The BT speedtester reported 16Mb/s.

When my line went wobbly (always on the 19th although interestingly this month it seems not to have done) I was mildly chastised for referring to 30Mb/s throughput off a 79Mb/s sync as 'poor'.

If I was with an ISP that doesn't claim to care much it wouldn't be so bad. But IDNet likes to talk a good game and they do employ people who know what they are doing. It's just such hard work getting past the front line 'defenders'.
