Better upload speeds anytime soon?

I've just been looking at some of the providers who do 2MB connection, sadly
though only offer 256kbps upload :-(

Does anyone know when we will start to see ISP's offering better upload
speeds? I have to upload about 14GB of files in the next 3 weeks. Not really
looking forward to it :-/

At the moment, the only alternative is SDSL, which gives you up to a 2 MB up
and down connection. It's rather expensive though, in the region of about
340 quid per month I believe.

Hi,
this is a limitation of the way ADSL uses the availble bandwidth, so it
is not possible to offer a higher uplink speed on a single line through BT.
However, have you considered multiple ADSL lines and bonding the uplink ?
This is possible using something such as the firebrick
(http://www.firebrick.co.uk). Setting things up is quite complicated
though, and currently the only ISP I am aware of that supplies this service
is A&A (www.aaisp.net.uk). Alternatively, if you are uploading lots of
small files rather than one large file, load balancing accross two links
would work (this shares the traffic on a per session basis rather than a per
packet basis).
The downside is that you will have to have multiple telephone lnes that are
all ADSL enabled to do something like this, but it's still way cheaper than
SDSL.

are you in an area where Easynet or Bulldog have unbundled services ?
The latter do 400k upload from memory.

Hi
What puzzles me about what you are saying is that in Denmark (where I just
moved to uk from) you can hardly get any less ul bandwidth than 512kbit with
ADSL.
And yes, this is on a single line too.
So it really can't be a limitation of the way ADSL uses the available
bandwidth...
Of course, it could be that uk dsl uses microfilters and dk dsl uses
splitters (i.e. a fairly big device put in front of the first telephone plug
which then seperates dsl and phone)...I don't know, but 512kbit is well
possible with ADSL..unless of course the quality of phone lines in UK is
worse than in DK.
Regardless, 512kbit _IS_ possible with ADSL, I had it myself for a long time
and I've had no problems getting 60kb/sec upload speed.

Jens Andersen

and the downstream speed ?

Hi,
I think you mis-understood my post. I did not say that ADSL could not
support higher upstream bandwidth. I said :

"it is not possible to offer a higher uplink speed on a single line through
BT"

The problem is BT's implementation of ADSL. They have reserved a 256k
channel for the uplink on all of their products, so will not provide a
higher uplink speed. As most (but not all) ISP's use the BT network for
their ADSL link, most providers cannot offer a higher uplink speed directly.

If you have a provider in your area that has equipment in the exchange (LLU
such as bulldog) they may be able to provide ADSL with a different
upstream/downstream split, but I have not heard of anyone in this country
providing that service. I suspect the main reason is that the only
advantage to SDSL is the semetric bandwidth, and if they provided a higher
upstream bandwidth, then they would not get any custom for the overprised
SDSL products.

For a while I had 2mbit/512kbit and i got around 200kb/sec download and
60k/sec upload.
(of course not at the same time...not really possible with TCP)
With 512/512 I had a max of 53kb/sec both up and down at the same time, but
this was mainly due to my QoS setup.

Get some decent software.
14Gb/256kbit = 5 days.

Why not? I'm not saying you're wrong, but surely there's nothing in TCP,
which is just a way of using IP for reliable, connection-oriented data
exchange, that says it can't be run full-duplex.

And as far as IP is concerned, it just defines the structuring and
routing of data across a network using packets - I'm not aware that IP
precludes duplex operation, either.
