Openfire: Protocol Support

# Protocol Support

Openfire provides full support for the XMPP protocol defined by RFC 3920 and RFC 3921. In addition to full XMPP support, Openfire also provides support for numerous extensions to XMPP that are defined through the XEP process at xmpp.org. This document provides a summary of that protocol support and is updated for every Openfire release.

This document is broken down into the following sections:

- Basic IM Protocol Suite Support
