Master node receives request for connection, checks # of concurrent connections to all avail. servers, request gets assigned to server with least # of connections. I leave the details of how to do it to you. I'm not the programmer here. > >There was a cool article in Linux Journal about a load balancing setup for a University (think it was in Canada). They did use a separate server to distribute the load and had separate IMAP server to authinticate as well as backup IMAP server. The diagrams in the magazine explained it better than I could. The setup was genius. Way more complicated than balancing ltsp connections need to be, but very informative none the less. > >Brian Kelsay > > > > > what about something like the intel eepro + series that can setup teaming via the e100 mod and their management software? I havent tested that feature yet but plan to in the future..
