Stop it girls!

I am not concerned about those brief regular spikes, only about the bump that is lasting from 6-10 pm. The former, I haven't a clue about. The latter affects my performance just when I need it to be top notch.

It has been apparent for about 48 hours now.

Sorry about head end misidentification Seph. My understanding of the network is not to be taken as read! What I do know is that the bumps are nothing to do with my home set up.

Roughbeast - it's the hump I'm concerning myself with. There's still the question I posed to Dwarven about what his circuit end is doing during the hump period. Is the hump a regular occurrence now? If Dwarven were doing something like p2p or uploading, if he stopped doing that, would the hump abate?

Are Dwarven's channels the same now as they were before the hump? The answers to these questions could paint a picture of why this is happening now that we've identified from the reverse traceroute where the bottleneck appears to be.

For my part, I have not done any P2P uploading or downloading for over a week. My bumps appear to be regular and unrelated to anything I am doing here. My only background uploading is for Livedrive. This occurs regularly throughout a 24 hour period and in response to changes in files on the drives it monitors. Its uploads are not limited to the mid-evening bump slot.

Here's a tracert taken just now. No bump ATM.

So, what you're saying is that there is regular upstream activity on your system much of the time. Is it not so that if you suspended that activity, the hump would be less pronounced? It's your contribution to the hump that I'm trying to get at. From where I'm sat (miles away), I couldn't say that what you're experiencing isn't influenced by what your system is doing. That's the challenge of diagnosis by forum!

Any change in upstream/downstream channel numbers when the hump started?

I will check channel numbers before and after this evening, and then let you know.

I understand what you are saying about my regular up load arrangements. However, these uploads are usually triggered by relatively small changes in small files on monitored drives. eg working Word or Excel files.They tend to be very brief upload sessions. Larger prolonged uploads only take place when I manually submit large video files or numerous music files to the Livedrive cloud. This I have not done for a week or so.

I also understand that my usage impinges on the over all profile of the TBB graph and that this applies whether or not there is a bump. My current upload / download patterns have applied for years now. I deliberately avoid evenings for P2P activity, such as torrents. The only thing that has changed is the evening bump. A few days ago it wasn't there, but now it is. My usage behaviour has not changed during that time. I may contribute minutely to the size of the bump, but I am not causing it, as I didn't with the virtually nationwide mid-evening bump of late 2012.

Isp's never learn from this, even ignition who has worked for VM. Still has the belief that when speed is increased usage doesnt go up by much. He did give me some stats to back up what he said but time and time again we all see isp's get themselves into bother when they increase speeds. They they say the same thing everytime after which is they were surprised by the increased demand.

My upstream channel hasn't changed since I got my speed upgrade at the beginning of the year, my downstream ones changed last week when I lost service for about 30 mins in the middle of the night.

I haven't done any p2p or uploading either, typically at that time of night Im playing World of Warcraft or watching tv :D

This seems to be down to some snap routing decisions over BT's LINX public peering. It appears to only affect traffic going over LINX' secondary public peering network, which incidentally, is where traffic from BT to TBB's ping monitor goes.

I couldn't find any other traffic that was affected, all privately peered routes were fine, all LINX primary links were fine, but everything over secondary was showing ~0.8% packet loss.

At about 5:15pm, the issues disappeared and everything went back to normal - I first noticed the problem when the throughput for the blu-ray I was streaming plumetted from 5MB/sec to 0.4MB/sec, and now that's jumped back up to full speed again too (actually it's peaking at 8MB/sec but the movie itself only averages around 5). That was transiting over LINX secondary the whole time, routing hasn't changed.

I'm not quite sure why BT is pushing so much traffic over the LINX secondary LAN, after all, they have ten times more capacity on primary than secondary. Whether it's BT's own routing to blame or like VM's issues a few months ago, due to an external network sending excess traffic the wrong way, I don't know. The issue seems to have disappeared abruptly for tonight so I can no longer trace where it is coming from.

on the 22nd the day before qas posted I had a little loss (almost gone but still there), then last 2 days its back with a bang, here ie yesterday.

http://www.thinkbroadband.com/ping/s...24-03-2013.png

However in the past 20 mins or so BT have made a routing change, my latency has gone up, I thought they changed a setting on my line but they havent so its something done on the routing.

Here can see the routing drop but with minimal affetc on latency on my gateway.

http://www.thinkbroadband.com/ping/s...25-03-2013.png

Here on my line but with base latency going up.

Sometimes it depends what the utilisation is like at the time you call, I'd use your graph as a reference and ask them to check upstream AND downstream at the times your graph looks pants.

From memory I think they can check back 3 days or so but if you get fobbed off use the ceo's office route

Goes without saying that browsing a few web pages like those would not be causing that graph.

Keep in mind VM have been known to say there are no overutilisation problems even if they can see the problem is kissing the threshold of the point it can be passed on to the network team. Other VM staff on the other hand will say they can see the issue but it hasn't breached the limits. Not sure why there is such a discrepancy between staff on the same problem sometimes.

Bottom line, don't trust VM when they say their is no overutilasation problems.

Agreed, and it was my first thought when looking how abrupt the spikes are, I just assumed the op would know when they were spanking their own connection Seph :)

It might warrant further investigation by the op

How do you get packetloss like that without the maximum latency increasing? Is it something to be with it being intermittent on and off over the course of every few seconds? :confused:

If memory serves correctly, they are finally due to fix the Croydon network this month which would cover thenry's area too. One could possibly assume that is a nod to those in the know about this. I left VM 4 months ago now, after waiting 7 months for them to fix my connection and then them telling me the new fix date was April 2013.

If those assumptions are correct, about time. The hardware must have been limping along like a lame one eyed dog just waiting to be put out of its misery.

Don't get what you are saying about the superhub though, unless more channels being added is causing problems with overloading the cpu of the hub?

TH ran some experiments and Ravenstar on the VM forum built on what TH had offered. Raven's experiments were well structured and it was possible to conclude that when wireless was ON (whether or not used) the ramping effect occurred; when wireless was OFF there was no ramping. We deduced (with no absolute proof) that the hib CPU was struggling, although why doesn't that happen to all SHs?

TH has more pronounced perturbations than Raven and that might be down to Croydon - I don't know.

Cheers, nice to know about these kinds of tests.

I would have thought that ping replies were so basic and low level that cpu load wouldn't affect them (or the silly low amount of ram) but im far from an expert in this area and have no idea how it actually works. Just did a quick google to see what chipset and if a single chip is used for all the functions but didn't find anything enlightening, except for a possibly too simple to be true way of bypassing the shubs security.

If ping replies are not dealt with by the chips own routines and is affected by firmware, that could be another avenue. But if its just a few people its unlikely unless something in that area creates a condition that brings it to light.

Interesting to say the least. If work on that area of the network is due or happening, it would be a simpler answer :D

That's exactly what I thought (with regards to all the blood!)

As for the traffic, it's really odd. Either a packet gets through perfectly fine, or it doesn't get through at all, there is no inbetween! As of 6pm, the blood all suddenly completely vanished. Hoping it stays like that, but a mystery as to what caused it!

Could make a guess that the gateway was confused and thought it was overloaded when it wasn't, causing it to drop icmp echo packets. Only scenario that comes to mind that would part explain it.

Fingers crossed it stays working :tu:

The maximum latency is limited by the maximum number of retries and delay time configured on the system (which signs seem to indicate have been reduced)

Because wireless is a notoriously variable medium and not all SHs exist in the same wireless environment?

Others have seen the same phenomenon with wired devices, so it seems certain types or patterns of traffic cause this behaviour on the SH, regardless of where it's coming from.

Got a feeling the firmware will get the blame again :D

Now if only you could use a web interface to upload saved superhub settings that had been modified to set usually hidden options, that allowed the shub to download a better firmware from a LAN tftp server. That would be ace ;)

Just did a quick google to see what chipset and if a single chip is used for all the functions but didn't find anything enlightening, except for a possibly too simple to be true way of bypassing the shubs security.
The chipset and configuration of the SH has been discussed here previously.

The cable modem components are integrated in the main CPU. The LAN ports are handled by a dedicated switch chip.

If ping replies are not dealt with by the chips own routines and is affected by firmware, that could be another avenue.
Ping replies are dealt with by the OS kernel.

Thanks for the info. Still not sure of its an atheros/broadcom/rtl type chipset though.

I did wonder if the actual IP stack was handled on a separate chip in the same way as the LAN ports being handled with a different chip. Specialised dedicated chips taking work from the cpu is common in other areas but I wasn't sure in router technology.

So the common factors with the ramping are the cpu and kernel/firmware.

Wouldn't let them give me a superhub, so never had one, never want one and will never get to try it ;)

When trying to fix their obvious utilisation problem, they stalled with a repull and palming me off with a vmdg280. Obviously none of that fixed their overutilisation problem but means I had beern downgraded from a modem to the 280. Didn't want to downgrade it any futher lol.

Many routers, including the Superhub, can use hardware accelerated NAT which does this, but only for traffic going through the Superhub and not to/from it.

Thanks for digging out the links for me. Exactly the info I was looking for. I was looking for info on the CG3101D last night which is how I came across the alternative firmwares. No one really wants to play with that stuff due to the lowly 8mb of memory.

Not gonna ask where you got your shubs. My vmdg280 left here in a blue body bag ;)

It has 64MB memory, which is above average and typical for high-end routers a couple years ago

Oodly someone else is now using the IP address I had but the IP Address TBB was tracking was the one given out by my AP and not the one VM gave me.

It replys to pings too. I find that confusing. As I said it's not the IP address VM gave me. It was one my router assigned to me. Not sure how or why

Fairly normal for a circuit that doesn't yet have two upstream channels at the Superhub.

Not really had a problem other that terrible buffering on TV Anwhrere (watching live channels) VM are fixing this over utilisation problem after I reported it Back in January (although they could,t explain why every other on demand player was working perfectly I.E Skygo, BBC iplayer etc)

Ah - TV Anywhere .... that depends on how you're watching it. For example iPAD (or laptop) over Wi-Fi; wireless is a Devil's science; and whether you are in rouer mode or modem mode.

I tried always.
Wired, wirelsess, all in router mode. Different times of day. Different channels.
All on my Macbook. Still the same result.

[http://www.thinkbroadband.com/ping/s...8-04-2013.html

This was your graph. The bit that matters is the blue - the average latency. By comparison with some/many of the horrors we see on the forums, this is a reasonable graph. Is it still like that?

Have you tried working in modem mode? If it's not external (congestion) then it could be the SH router tying itself in knots as has been reported (with more radical symptoms) in THenry's Crawley thread and in Ravenstar's thread in the VM forums.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 
yes you are right too many vm custemers on even shitter lines , just like i was last year my blue average was very high the graph was full of color

the jitters are bad also 3 moths ago it was perfect and only just been fixed for H.U, i can see its slowly going back to crap,

also max latency does matter its not as important
2 upstream channels will properly be the only thing to ever fix it

this is today i am getting random packet loss

But rhe packet loss would be a worry. It is often due to upstream noise, which isn't reported in the SH. Is there anything in your stats (like varying upstream power levels) that might indicate something out of whack?

VM have had to remove traffic from some more Peering links because they were not working correctly for Sony provided content from multi different CDNs.
So will this increase ping times on other links during heavy traffic hours...

Ok so you don't know why the ping time has dropped instead of increasing even though there are now LESS peering links to share the load now that Virgin media Turned the Broken Peering links OFF.

Its OK you can POST you have no IDEA why the ping is now Quicker/Lower than it was when there were lots of peering links provided buy VM. Now that they turned off 2 Peering providers links to fix download problems on there network...

Its OK I was just expecting Ping to get higher now that there is less room on there networks as they have shut network pipes down.

What on earth are you on about.

You've stopped seeding. Load on your line has gone down. Therefore latency has gone down.

What has VM peering links got to do with your torrent seeding?!

Why? Unless the network is at 100% load there should be no change in ping whatsoever.

On the other hand, VM prefer to use slower, cheaper links by default so by switching them off traffic is forced onto faster, more expensive paths.

Nonetheless VM has dozens if not hundreds of peering links. What on earth makes you think changes to 1% of their network would have any noticeable effect on your torrents?

Another +1 on Sky fibre over here, although BT infinity does look equally as good. Plusnet is also meant to be fairly good if you are on a lower budget
