Comparison of instant messaging protocols
The following is a comparison of instant messaging protocols. It contains basic general information about the protocols.
==Table of instant messaging protocols==
Note 1: In ~usr@a.b.com, the a.b.com part is known as the "hostmask" and can either be the server being connected from or a "cloak" granted by the server administrator; a more realistic example is ~myname@myisp.example.com. The tilde generally indicates that the username provided by the IRC client on signon was not verified with the ident service.
Note 2: In usr@a.b.c/home, the home part is a "resource", which distinguishes the same user when logged in from multiple locations, possibly simultaneously; a more realistic example is user@xmppserver.example.com/home
Note 3: Scalability issue: The protocol gets increasingly inefficient with the number of contacts.〔RFC 1324, D. Reed, 1992. 2.5.1, Size〕〔(Functionality provided by systems for synchronous conferencing ), C.v. Loesch, 1992. 1.2.1 Growth〕
Note 4: One-to-many/many-to-many communications primarily comprise presence information, publish/subscribe and groupchat distribution. Some technologies have the ability to distribute data by multicast, avoiding bottlenecks on the sending side caused by the number of recipients. Efficient distribution of presence is currently however a technological scalability issue for both XMPP and SIP/SIMPLE.
Note 5: There have been reports from users that the antispam filter is used to censor links to other IM programs and some websites.
