I notice that I get high latency spikes when I upload or seed.

That makes sense.

but the average (blue) latency was never so high, just the maximum (yellow) latency.

this is from yesterday,


http://www.thinkbroadband.com/ping/s...23-11-2014.png

can you explain it for dummies like me that don't this language please?

I restarted my hub yesterday to drop it which it did though my seeding didn't go back to high levels again that it was doing at the time.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 
In simple language, when you are busy downloading, seeding or whatever of that type, this traffic takes priority over pings to/from your system. SO the ping latency must rise.

cheers, but as I said the blue is never that high its normally the yellow.

is this usual the case?

I never see the blue go that high.

It could be one of two things:

1/
The stuff your system is doing is not exactly the same in load terms as on previous occasions - for example running upstreams and downstreams together.

2/
There is additional utilisation elsewhere on your node.

Blue that high is completely normal thanks to VM's bufferbloat.

You would have absolutely no problem wriggling out of your contract with a connection like that, best route imo is contacting Virgin via social media asking them to check on the utilisation of your connection, chances are they will be well aware of it being hammered and be able to advise on a suggested fix date.

Beware though, these dates come and go and can take 12 months or longer to fix, however the beauty of this is you can ask for a reduction off your monthly bill until it's fixed or simply leave with no penalty once you've spoke to a decent customer service person that is.

My advice is, if your a gamer and need low jitter then look elsewhere, if your a habitual downloader, stay put and ask for a discount.

We have both VM cable and BT Infinity.

My son's a gamer (CoD) and his PC is usually on BT Infinity - except that he often asks to switch when poor latency shows up on Infinity. He generally gets better latency on our VM circuit.

It all does need thinking through.

Ignitionnet 27-11-2014 08:57

Re: Think Broadband Ping Monitor Results (POST YOURS)
 
You'll probably see an improvement.

http://www.thinkbroadband.com/ping/s...27-11-2014.png

By its very nature cable is more prone to latency issues than properly configured xDSL.

qasdfdsaq 27-11-2014 09:10

Re: Think Broadband Ping Monitor Results (POST YOURS)
 
Indeed, the underlying tech is more prone to it but it's all in the implementation. Depending on area, line quality, and the so forth, even on a high jitter VM line you could end up with lower average latency than even the minimum latency on a colocated FTTC connection if you're unlucky enough to get a crappy routing path and forced interleaving on your line that you cannot turn off.

It probably depends on what kind of games you play and the times at which you do it, if you play a lot of driving games like Forza, then you might not notice too much difference but if you play FPS games like call of duty, you could well notice a benefit, there's no guarantees but it certainly looks like your part of VMs network is suffering under the strain.

You pays ya money, you takes ya chance :)

qasdfdsaq 27-11-2014 19:09

Re: Think Broadband Ping Monitor Results (POST YOURS)
 
Some driving games might be extra sensitive, as they lack lag compensation. MMOs I find to be the least lag or jitter sensitive IMO, especially as they tend to have 500ms+ server lag built-in anyway.

Wonder if new hardware or a new JunOS release have caused some problems?

There are 25 'servers' in Uddingston, and you and Martin could connect to any one of 7 of them. Each of those 7 can serve 10s of thousands of customers in hundreds of separate groups.

Unless you guys are within a couple of streets of each other you aren't sharing the same things throughout, and your issue seems pretty local.

Understood - but if the TBB graphs were from the same day, the red bits were different (e.g. see 4pm 27-Nov). And it was the TBB graphs that were posted as evidence.

The supercore, the -bb- nodes have been Juniper for a while. When I joined the company back in 2003 they were M160s and have been steadily upgrading since with the core nodes around that supercore/backbone being Cisco kit replaced by Juniper kit subsequently.

One thought that comes to mind is that you're running torrents with hundreds of peers connected and overwhelming your Superhub.

The ping times suggest you're constantly seeding.

Sephiroth 30-11-2014 22:07

Re: Think Broadband Ping Monitor Results (POST YOURS)
 
Looks like intermittent noise on the upstream. This is deduced now that you have posted the modem stats. An upstream problem can be confirmed if your upstream power is not stable and reaches 54 dBmv.

If the high power were due to noise it'd come with packet loss on the TBB monitor. If power is ramping up because periodic maintenance, which uses QPSK, isn't being seen then the 16QAM data bursts will be lost too.

I do seed a lot mate but that is nothing new, it was never an issue in the past, only this week

I mean these outages are happening when am not seeding, like when the computer is switched off

I knew you'd come in on that. But if the noise occurs only at the time of the resets (which is possible) then we have an explanation.

If he posts on the VM forum the team there will be able to say what's happening. Of course there are the other possibilities of SH failing (I doubt that) or a problem in the common part of the network in which case neighbours would see the same.

Blairhoyle 30-11-2014 22:35

Re: Think Broadband Ping Monitor Results (POST YOURS)
 
this is a joke, that is the 4th outage now since 6pm.

I can't understand how my seeding has anything to do with this...I do a lot of seeding around the weekends and have done for years and NEVER have I had this amount of outages in one day, never mind just this week, in fact it never happened period.

A fella I spoke to on the Paisley connection (I assume that will be via Uddingston) said he's had a similar problem over the last 2 weeks.

I've just spent another 30 minutes on to the phone trying to get through to VM with no joy, hopefully I get a response to the thread I made on the VM forum + I've sent a complaint.

Doesn't explain how you deduced it from the modem stats. If there is no noise the upstream power will normalise straight away - as soon as periodic maintenance and response are exchanged CMTS will tell modem to back off to avoid the modem causing problems by overpowering return path laser.

To perceive noise as a cause from modem stats you'd need to see high upstream transmit power at the time of the issue.

Needs a tech either way. The upstream transmit is a little high and out of kilter with the forward path.

EDIT: T3 count would be useful.

Will post it in the morning mate just away to bed, my computer is off now so will be interesting to see if there is any outage.

Was seeding yesterday and had no outage then 4 quite quick today

The high upstream power shown in the stats was what led me to the possible deduction. So I asked Blair to see if the power was ramping.

Incidentally for Blair, the T3 count is best obtained IMO by using the stats from the ROUTER STATUS link at the top right of the GUI screen rather than logging into the GUI.

There would be packet loss during periods of high upstream power if they were in response to noise. Upstream power rises because there's no response to station maintenance, either because it was drowned out due to noise or some other impediment or more rarely because of a problem on the downstream.

While power is ramping up TBB monitor will show loss as the data (ping response to TBB) fails to get through to the CMTS along with the station maintenance.

I've suspected upstream because of the high power level. Igni has correctly pointed out that upstream power ramping can occur because the downstream is playing up and the modem can't respond to maintenance requests it doesn't understand.

Igni has also said (more or less) that there isn't enough evidence of packet loss in the TBB graph to signify an upstream problem.

On balance, he's prolly right! He does point out that T4 events due to the downstream are rare-ish.

Anyway, it takes three or four days for the VM bods to reply over there but they'll tell you what's going on.

thanks for the response guys.

will VM forum be able to deduce what the problem is by simply checking from their end?

I haven't posted these stats on to my original forum post and I don't want to go back and post them because I think that 3 day wait then starts over again.

do you suspect this has happened off the back of the 152MB upgrade?

Sorry for the questions, I've been following you two's conversation and I must admit, it would probably be better off written in Chinese for that is how much I understand of it :D

I posted on VM forums and got this reply from John

"Your power levels and modem stats are fine. Looking at your connection I can see your upstream utilisation is getting high at peak times. This would explain the ping spikes though it is not very severe and quite short lived so we're unable to raise this to networks."

just thought I'd let everyone know that VM finally responded, not to my thread on the forum, it was a post on someone else's thread:

apart from the very occasional peak time spike this doesn't look to be related to high utilisation, but more an issue with high upstream power levels reported by your SuperHub.

Got an engineer popping on Friday morning I think, I assume that should sort it, but I've read others saying that not all the engineers visits solves these issues.

Phone them up and report it. Virgin won't do anything unless you book a trouble call against the issue. Path of least resistance for them, you can sit and stew at home but that costs them nothing. Paying someone to answer a phone call costs them money and when enough of those happen, it becomes cheaper to fix the problem.

raise an official complaint via the website mate.

maybe chance your arm and make a comment on this thread

I did that yesterday just to add to the conversation and had a staff member PM me today to arrange an engineer visit.

got a response from a couple of lads who I showed my readings to.

Quote:

The upstream is well out! It's either going to be an bad f connector, too many splitters before the cable reaches the hub or an area issue.

An attenuator will not reduce the upstream as they now use wideband attenuators which will increase it. You might find the guy will fit a powered splitter in the house. Just make sure he gets it below 46/47 on the upstream and you won't have any issues. Also ask him to swap the modem just to make sure.

Indeed. The TBB graph merely provides potential corroboration for modem stats and anecdotal performance reports.

to be honest and fair about this, not everyone that uses this forum actually has the technical know how, experience or knowledge what the vast majority of these issues are.

And I include myself in that.

An outage shows in the modem network log. Sometimes there is a corresponding red line in the TBB graph. Corroboration is necessary, IMO otherwise people are wasting their time trying to help.

in my case there is clearly a problem, my hub is resetting (outage, whatever you want to call it) every day, I've been told my upstream levels are slightly high.

I have to constantly enter my pass word in to re-connect my Sky box to wifi.

Normally my connection has been rocked solid, however the last two weeks has seen a daily disconnect from the internet for about a 2 minute period. I had 4 disconnect in 3hours last Sunday whilst I was on Skype, bloody annoying when you are trying to get work done.

I'm posting stuff up to allow others that may be suffering the same problems or for others to make a suggestion.

That's fine, Blair except that the stuff being posted is incomplete without the modem stats. That said, it's clear that you need VM input. Did you provide a link to your thread in the VM forum?
