Hi Jimmy
First off, you have to be careful about average use and useful use. If you only use your app for five minutes during a 24 hour period and it happens to use a huge amount of bandwidth, that will still average out to a very low average bandwidth use and could skew your calculations.
Citrix claim a minimum of around 25Kpbs, I believe, but you wouldn't be doing very much with that - maybe using a very basic application. To do full screen Windows with a couple of apps, you'd be looking at significantly more, especially if you threw in drive mapping and other features. That's not a criticism of Citrix in any way, it's an excellent product - it's just an example of how it's easy to get caught up with marketing 'minimums'.
For a 'typical' home user, accessing the web, doing StarOffice work, etc, Sun recommend a 512Kpbs broadband link to allow 'bursts' of 300Kbps. But that's running a full Sun style desktop, or connecting to a Windows session and displaying similar stuff.
That said, we've also seen Sun Rays using as little as 70-75Kbps during sessions.
I'm working on a trial that will replace dumb terminals - there'll be no graphics whatsoever, just a terminal that the Sun Ray would be accessing so we're looking forward to seeing what bandwidth that will require, as it should be minimal.
I know of a customer using 5 Sun Rays separated from the Sun Ray server over a 2Mb leased line. The Sun Ray server is accessing Citrix apps, rendering them on the Sun Rays at the end of the WAN. The customer claims the line is only used by 20%.
As always, your mileage may vary - all the thin client options have vastly varying marketing averages and useful figures. The best way will be to get a small pilot going to see what your requirement are.
Regards
Chris

When I am calculating minimum bandwidth requirements for Sun Rays how do I do it? I know that RDP need about 19k per user... more depending on settings.
