I was trying to find a decent explanation of the differences between SIP and SIMPLE the other day for a presentation for a customer when I came across this useful link which explains all of the acronyms and gives an overview of what each protocol does during a session. http://web.archive.org/web/20051210032337/http://www.microsoft.com/technet/prodtechnol/winxppro/plan/rtcprot.mspx
SIP (Session Initiation Protocol) is a fairly obvious one but SIMPLE (SIP Instant Messaging and Presence Language Extensions) blew me away. I’ve been presenting these sessions, and wanted to know each acronym (a pet hate of mine is where presenters don’t know all of the acronyms on the screen), and I’m blown away and impressed by this one. It gets my vote for the longest Microsoft acronym I’ve discovered in messaging so far..
