I have had no humping recently; time to have an affair perhaps.
Ignoring the massive blips, entirely due to me running uTorrent and Livedrive without reins, my graph has been looking pretty good.

I appear to live in a low contention and updated area so I only usually get problems when there is a regional or national issue.

Here's the graph for Monday 13th.

That is 1 of the best VM graphs i have seen in modem mode.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

That surprises me. Surely other areas that have been re-segmented and re-carded will be getting similar profiles.

Here are Tuesday, Wednesday and Thursday from last week. Any blips or reboot lines are due to my activity.

I think you have alot less yellow, although i think my connection is great apart from the 5 day issue last week. :)

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I also must be in a low utilisation area, last nights big jump was me getting some stuff via torrent.

Is that with a SH2 in modem mode?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

No thats the SH1 in modem mode and Asus RT-N56U router running Padawan firmware.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

To be honest I don't think there's a lot of difference between SH1 and SH2 in modem only mode. It is the WiFi that is the problem with the SH1.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Yes that is true which is why i am glad i was on the trial for a SH2 so got 1 free as i have no use for a separate router. :)

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Depends what you want to do with a router. SH2 will do they basics very well.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

But only the basics.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Well heres my fine piece of modern art for today...

Obviously not standard congestion. I take it a reboot of the shub starts the hill at a lower latency again? Is this a shub or UBR/Chasis bug? Or something to do with signals/frequencies being multiplied/collided/anything else i'm clueless with. Almost reminds me of a memory leak, but with network packets...

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Seems all I can get from it after consultation from Seph is that it is congestion on the upstream causing the upstream buffer to fill up at the modem (causing the router resources to be consumed while BPI is working overtime) - of course just a theory but in my eyes seems the most likely, i've been at my office all day and no-one has been in, so that's all with zero usage at my end. ill do a power cycle now and see what happens.

Ultimately, if my theory is correct, its technically a firmware bug, but if VM were to keep utilisation at acceptable levels it would be a non-issue, but this is VM we are talking about!

Craig,

As I mentioned earlier an exhaustive set of controlled tests were performed and reported here.

Although there was much postulation, and this ramping was shown to occur irrespective of user load, there was no conclusion as to cause. Turning firewall off, turning wireless off all reduced latency. But the matter was not resolved.

Ravenstar's SH2 did not display this ramping, and my SH1 never did either.

So now to further speculation taking into account what QTX has just said. In the SH2 trial, Ravenstar's SH2 suffered from the BSR incompatibility issue associated with BPI/TEK. I don't know if TH at Crawley is on a Motorola BSR and what Craig#s CMTS is. But if it is a BSR and we can chase all the other users who have reported the ramping and get the question reopened.
