50M : Think Broadband Ping Monitor Results (POST YOURS)

Mine is looking a bit better as of late.. upstream bonding has helped alot, I think I will wait until the fix date provided for extra capacity to be added and see how the connection is then before jumping ship to Infinity.

Ah right cool, it would probably be better if I was in modem mode I assume, they said they were doing some load balancing/adding extra capacity over the next couple of weeks when I called them about something else so thought that might be the cause of the spikes but if it's mainly the blue that matters I am very happy

[Sephiroth]

Not necessarily better in modem mode because it's still your router that's linked to TBB. But the CPU load on your own router will be lower than on the SH and the contrast between peak and ff peak on TBB should be less marked.

The blue is the average. That's why it matters.

I thought in modem mode the modem itself still sees all the traffic while filtering out the correct packets (BPI) - so surely the marked difference between peak and off peak wouldnt change? (correct me if im wrong)

Yes, the modem applies BPI - but that is an in-line function and is rate limited by the configuration file. But the arrival rate of TBB pings is influenced by circuit utilisation as are router responses which are also sensitive to whatever else the router is doing.

When I'm in modem mode, the difference isn't as marked as when I'm in router mode (my current mode). I'm not currently at home. So what I've pasted below is a TBB with my own system quiet. The SH2 is doing the TBB work.

Just logged on to my nans superhub to see how her 30mb service is doing, and noticed she has 8 upstream channels ? Never seen this before, she's connected to the same UBR as me too. 8 downstream channels for 30mb is a bit odd no?

[Sephiroth]

The number of DS channels is not a function of the tier you are on. VM aim that everyone will have 8 DS channels so that eventually you can hit 200 meg or more (8 channels supports 400 megs but SNR has to be high all the time and thy'll have to resegment so as to avoid serious congestion).

Two US channels allow up to 40 meg at current modulation but the frequenxy is noise sensitive which makes it tricky increase the bit density (modulation increase from 16QAM).

[jarrodstrachan]

Ah right, wasn't aware they were doing that.. not that it will make much difference to my connection as I think downstream utilisation in my area is fine. Especially with having 8 channels available.

I was actually speaking to a friend yesterday about whether Virgin will offer 200mb in the next year or two. I know they did a trial a while back, but I don't know the ins and outs..

Connection Thursday/Friday





Connection Friday/saturday

Have these swings in connection constantly over a 24hour period, usually it is more of the Friday/Saturday variant though.


Several users in same area as me ( rm7/8 ) get the identical red spiking at identical times, Apparently it's a 5 month running fault now and i have been informed by my "customer complaint liason" that ""Networks have currently engaged our network partners Cisco and Telindus in trying to locate where this problem is, hopefully we'll have more information over the coming days""

We all suffer from massive amounts of t3 and t4 timeouts, currently 784 t3 timeouts and 28 t4 timeouts

Jesus, I think I would get a full refund for that connection immediately and use the money towards an ADSL connection.

I'm glad they're trying to put EVERYONE on the same number of DS channels. It just makes sense, really. Technically, there's no real limit to the number of channels they can have though, is there? I mean the SH itself might be a limitation, but DOCSIS3 doesn't have a hard limit or anything, I don't think.

I wonder if new hardware would be required to go above 8 DS channels. If it is, I'd imagine they'd just roll out DOCSIS3.1 hardware instead.

200Meg would be nice, if only because it would be 120Meg under STM :p

AFAIK DOCSIS3 = 24 (source= the (euro)CableLabs specs).
