# Protocol Support

## Introduction

Openfire provides full support for the XMPP protocol defined by RFC 6120 and RFC 6121. 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:

- Core XMPP Server Compliance Support
- Web Compliance Suite
- IM Compliance Suite
- Mobile Compliance Suite
- List of other XEPs Supported
- Footnotes
