Hello Dod, At first tought I should go for first solution because of a few advantages.
- server updates as you say yourself - application is splitted separate according the job it does. The concentrators dealing with the clients and the proto, between concentrator and main server you can exchange data with same or another protocol depending what fit's best, or middleware. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Tuesday, January 3, 2006, 10:41, Dod wrote: > Hello, > I am starting a re-write one of my ICS-based server to be able to > handle 15.000 permanent cnx smoothly.
