Heh one debate is over anyway:

About Me

Ignition
Yes, I'm the one who posted on Cable Forum under this name *smiles*

Altis, noted, I was just a bit confused by the relating of windowing to Ack Frequency. I'm also going blind sifting through 100MB TCPDumps right now which makes one a touch touchy - my apologies.

Yes it does, you're quite right sorry. I seldom spend more than a few seconds scan reading blogs. Bad habit but short on time :erm:.

Re: One Way Internet

I was talking to my mate about this thread earlier and we came to the conclusion that instead of having 20meg download speed you should have 20meg of bandwidth and be able to configure it however you like, so if you want 10 up and 10 down you could do it. Wonder how much they'd charge for that eh?

Re: One Way Internet

The drama that's kicked off on that blog is fantastic, I guess it got under someone's skin :D

Back to the point of the thread.

I have to admit, I do not understand why upload is so low on the 50 meg (assuming both TraxData2 and Ignition are correct, and I have no reason to believe they aren't). I can understand that when the broadband hardware was originally installed, upload wasn't as important as download, so the cable cos considered high download as a higher priority than high upload, and to some extent, this has meant that the uploads are limited (at least on the lower tiers) by old hardware. Upload was not as important (then) as most people hardly (if ever) uploaded anything.

Trouble is, that since then, we have had all manner of services spring up that will happily use a lot of upload. Things like file sharing systems, video sharing sites (such as Youtube) and Photo sharing sites (such as flickr). Combine that with the fact that a lot of people are emailing their own media (such as digital photos) to family and friends, playing/hosting online games or hosting their own websites, all of which take a lot of upload bandwidth.

VM have the excuse that when the hardware for the lower tarrifs (maybe not so much the 20 meg) was installed, people didn't do that stuff. 50 meg, however, is different. They are installing the hardware now, so people would have been doing that stuff when they planned the installation. They should have taken it into account.

The trouble is, I don't think VM actually want people to use their connections. They just want a lot of people to sign up to 50 meg, then just use it to check the odd email.

The network architecture being put in place for 50Mb/s only allows for a single QAM16 Upstream Port to serve the DoCSIS 3.0 Bonded Group. This is because of a lack of upstream channel availability (this could be improved with access network maintenance/upgrade)
Therefore there will only be around 8.5Mb/s useable bandwidth available to all 50Mb/s & 20Mb/s customers located on the bonded group.
If much higher upstream speeds where provided it would likely lead to upstream congestion..

In my opinion they would be able to support 2-2.5Mb/s upstream with the proposed implementation.

It is my understanding that contrary to what Traxdata2 says VM have not yet entered the 'Product Trial & Pilot' phases yet.

In my view they will look at the trial and pilot data with regards to upstream channel utilisation with a view to tweaking the upstream and going forward they will be looking at ways to improve upstream speeds (QAM32/64, 6.4Mhz Channels, SCDMA on <20Mhz spectrum, channel bonding etc)
It is not beyond the wit of VM to blow the competition out of the water with respect to upstream speed.. It just has not been in their focus over the past few years.

I have it on good authority that this is about to change:)

Re: One Way Internet

Does whoever spoke to Ignition know this Bug?

You appear to have just contradicted what they said by saying that the network needs upgrade and maintenance.

Re: One Way Internet

I see that blog is getting interesting to say the least :shocked:

Re: One Way Internet

It is pretty entertaining. It's like a soap opera.

Would be nice.. But HFC Networks aint built that way.. They are very much Downstream heavy in nature, due to them being primarily built for TV.

So unless you want to pay for the overbuild :)

Re: One Way Internet

I thought us on the top tier of service were already paying for some sort of overbuild rather than pay for advertising?.

Evidently Virgin don't want to looking at the amounts spent on overbuild recently.

1 normal upstream channel for the wondrous new product and 20Mbit customers is a joke and just highlights the attitude of doing it for as little as possible while giving maximum PR impact and bragging rights rather than doing it right even if it's not as visible or cool. :(

Re: One Way Internet

I dont upload so I'm not really bothered about what ratio I am getting. As long as it works I'm happy :D

Re: One Way Internet

Bet you do :)

EDIT: Your entry to the CF Photo Of The Month for example had to get their somehow, and if you have any online photo albums... ;)

Actually, as I understand it, VM take a loss on the highest tier, and use profits from the lower tiers to subsidise it.
