Multiple sub office connectivity to a datacenter.

I have a couple of questions and hope that others have already solved
this problem. What is the best way to connect multiple UK sub offices
to a data center also in the UK.

I have a situation where I need to connect perhaps 20 offices to a data
center.

I forsee the following requirements:

1. Dual path or at least via seperate ISPs or with ISDN backup.
2. SDSL or symmetric connectivity if frame relay (4Mbps connectivity)
ADSL would not work for the application.
3. Cheapish (ie preferably not BT's MPLS based solution).
4. Reltively quick to turn up a circuit (less than a month).

Am I correct in assuming that these are there are the following options
for doing this or have I overlooked something:

1. Dry copper point to point circuit terminating in datacenter rack
with SDSL modems on each end.
2. SDSL circuit from unbundled ISP

I guess something else that I will have to consider is the bandwidth
charges from the datacenter. I would like to save on these by perhaps
using an ISP that terminates in their own datacenter. At the moment we
have not selected a Datacenter for our equipment.

Hopefully someone out there has some insight or pointers on what to avoid.

Have you considered a Terminal Server solution?

I suggest you talk to a specialist business providor. Say PIPEX, DEMON or
NILDRAM

I have but this resticts many things. Firstly I don't plan on building
a solution around Windows. Secondly, even a terminal services solution
still needs bandwith and needs a central server located somewhere.

which leaves out a number of others, such as Easynet (interest: I have a
few shares in the firm) and smaller, technical specialists, such as AAISP
(www.aaisp.net) which may be more able than several big ISPs to understand
the questions and suggest reasonable solutions, BICBW :-) Peter M.

Ah well, just a thought. We run systems for several clients, with
servers in Redbus http://www.interhouse.net/ using mostly Terminal
Services with ADSL connectivity in client offices and variable
speed connectivity (up to 100Mbps) in Redbus. TS solutions use
surprisingly little bandwidth to get good results. A 2M ADSL line
can easily support an office of 20 users for most general
productivity tasks.

Obviously the asymettry of ADSL *is* oriented the correct way around for
a terminal server based approach, but even using citrix with speedscreen
the screen update latency can be noticable, nothing annoys users like a
lumpy session ...

You haven't provided much info. For one thing, does this need to be via
Internet or are you looking for a private network? For example, BT's
IPClear (and similar products from other telcos) offer ADSL style
connectivity to a private network that can terminate at your data centre.

This could be via the internet. I expect that would be the most cost
effective method. My concerns are line contention. Is the contention
imposed at ISP interconnect gateways or within their network?

If they were at the network gateway would I be able to reduce congestion?

Thanks for the info about IPClear. Will go and look at it.
