IP Stream vs DataStream

IP Stream vs DataStream

I've searched google already and it doesn't help much.

From what I've searched on google "it's technically the same as
DataStream with a bundled IP router at BT's end but it's pricing is on
a completly different basis."

What is the point of having it if it is technically the same?

What does Datastream offer that IP Stream doesn't offer?
Can someone provide a list of differences?

I've looked but it is very difficult to work out what the difference
is.

Fast24 offers Datastream as it's ADSL product, I need to know the
differences to IP Stream.

There is one post here

BT SINs at http://www.sinet.bt.com/
For example, see SIN386, SIN388, SIN374, SIN347

Any ideas?

> IP Stream vs DataStream

It's what happens at the exchange end that is different.

With one (and I can't remember which), at the exchange, the data is routed
over BTs backbone.

With the other, the data is routed onto the ISPs own network.

in simple terms, IPStream is a fully bundled product offered by BT to
service providers. As an IPStream reseller, a service provider needs little
network infrastructure - BT bring all their customers traffic into a chosen
location using a bit fat central pipe. The only thing the service provider
needs to worry about is how many fat central pipes to buy.

Datastream on the other hand is more complex. A service provider needs to
buy a connection to every local exchange they want to provide service to,
and need lots of short connections (for it to be financially sensible) into
the BT network to haul back the exchange connections, and every local
exchange connection needs to be planned. The datastream product is targeted
at those service providers who have a large network of the own and want to
make use of it to provide datastream services. But it can be cost effective
for a service provider to choose this option if they have sufficient scale,
and gives the SP more flexibility in the services they want to offer.

From an enduser point of view it really doesn't make any difference. A
standard 512k service on datastream and one on ipstream for example wont be
any different from a user point of view....

If there aren't many users using Fast24 (via Datastream) at my local
exchange, will I notice any speed improvements?

Change over from what to what?

well the difference right now is that DataStream takes MONTHS to get
installed!

Between ISPs.

not so. BT have standard 10 day lead times for IPStream and Datastream
connections.

Probably. But that applies to IPStream also....the less people on your
exchange, the more likely hood of getting better throughput. This applies to
datastream and ipstream - but it isn't a hard and fast rule. There are
additional issues which affect throughput other than the number of customers
on the exchange (eg. service providers transit capacity, IPStream central
pipe capacity, etc.)
