A bit of upload fluff would be nice too, only ever hit 9Meg up on our 100meg connection, but its good we're getting the extra 10Meg down :D

I think it will happen once VM has rolled out 100mb to all remaining areas.

You also forget that downstream upgrades don't go anywhere near the level of increased usage that upstream upgrades bring, there's only so much to download.

4 -> 5 downstreams is a far more complicated job than 5 -> 8. It needed line cards to be replaced in the case of BSRs and a shift to I-CMTS architecture in a number of cases on the Cisco.

I would recommend looking at how the line cards are broken down, multiples of ports per line card, etc, it would make more sense than assuming that the line card replacement required to go from 4 to 5 or in the case of many Cisco 10ks even just 3 to 4 downstreams is replicated in going to 8.

I'm not aware of it being PR talk, I've not seen VM make big news of this. Beyond us nerds no-one really gives a monkey's about how many downstreams VM are using in each service group.

Theres your mistake.

People on 100mbit can find enough to download to keep it busy pretty much 24/7. Tons of media content out there. Given it only takes 1-2 in any given area to cause problems its quite easy to see the serious misjudgement thats occured.

Next year when the xbox 720 is released microsoft whispers are the games will be download only no physical media, games I expect will be 10-40gig in size on average, demos will likely be at least half that size as well. But in terms of media currently available there is raw bluray been released multiple times a day at 40+ gig a pop very capable of keeping 100mbit lines busy.

Someone with your experience not only should think usage will increase, they should expect it.

Incidently VM have now officially confirmed downstream is "very highly" utilised in my area and its finally been escalated.

I remain curious of course on what 50mbit is getting of course and its good the fluff is been added in regards to complying with regulation but at the same time I feel my concerns are very valid.

Right, clearly there are people who have the storage and indeed the will to download 30TB/month.

It's no mistake it's a combination of common sense and fact. A 100Mb line pulls 1TB/day, over 20 full Blu Rays, even storing these on optical media would be impractical. Of course there's sufficient content to download 30TB/month, one could just re-download the same file over and over again all month, does this seem likely?

I fully expect usage to increase I'm not naive I just think, as usual, you're hijacking a thread because of your own service issues and with that in mind will not respond to further posts from you in this topic.

IMO Chrysalis is perfectly right - VM need to concentrate more on alleviating oversubscription by whatever means works and I expect that will be traffic management rather capacity increases. "Adding fluff" and increasing XXL speeds to bring them closer into line value wise with XL and 100 is purely for marketing purposes.

Oversubscription has moved me from happy bunny to definitely a lost customer long term (when I can get Infinity) and quite probably a lost customer immediately to Be ADSL once I've looked at the costs involved - this following a supposed upgrade which still leaves my CMTS oversubscribed by my definition but not VMs.

Hi,

Sorry to be a bit thick, but I figure if I don't ask, I won't find out:

What is the nature of the overhead?

I presume 102.4 Mbps is raw data rate, and 98 Mbps represents the encoded ethernet packets (frames? datagrams?)
If so, what is in the 4.4 Mbps? and is it encapsulated? Is it associated with the modulation / demodulation process?

Or am I barking up the wrong tree entirely?

Phil.

IP and TCP headers Phil, 40 bytes per 1500 byte IP datagram leaving 1460 bytes for usable data.

Oh.

Cheers Ignition. I was hoping it might be more interesting than that!

:)

Download speeds of over 100Mb (110mb), including the fluff on top, would at the moment be pandering to a completely unnecessary arms race.

It will take some time for video, game and data technology to catch up with 100Mb, let alone 200Mb or 400Mb+. If commerce really needs that much they can get it now anyway. It will be some time before all but the most BB hungry student houses will need even 100Mb.

I agree with all those who say that from now on ISPs should concentrate on increasing capacity and moving towards connections that are more symmetrical. e.g. 10:3 would be fine for most of us. Quality of service should now be the mantra. VM needs to take that on board or become 1st choice only where they are the only choice.

It's nothing to do with an arms race it just relates to how the products are advertised. The rules are being changed so that ISPs can only advertise the speed 10% of their customers can achieve.

Without the fluff people can't get 100Mb throughput.

As far as the rest goes 100Mb is not getting upgraded to 200Mb any time soon so no worries there. 200Mb as a new tier around Olympics time.

Perfect for scrubbing any benefit from 8 downstreams and of use only to those addicted to downloading by the TB daily. Oh - and the marketing wonks.

Traffic Management v2 will deal with that.

heh you read my mind, I guess those who get the 8 channels last will probably get just in time for 200mbit.

Dissapointed ignition now wants to ignore my posts, and traffic management v2 may deal with it better than whatever is in place now but at the same time traffic management shouldnt replace capacity, it should only complement it.

In terms of storage the content will either get trashed or burnt to removable media. Some people download and burn all day long.

Any info on "Traffic Management v2"?

I reckon some people are actually magpies who download and burn all day long, but actually they transfer their largess to the cloud because they can. They then say that they have a massively awesome collection of music and films in the cloud which they never watch or listen to. However, this is cool because wow it's awesome man. Bring on 400mb/40mb man.
