== Features ==

The freeDiameter implementation supports the following features:
 * Full support for the '''Diameter Base Protocol''' defined in RFC3588 and [http://tools.ietf.org/html/draft-ietf-dime-rfc3588bis-21 draft-ietf-dime-rfc3588bis-21], including:
  * Native IPv6 and SCTP support.
  * TLS support (mixed port or separate port), even for SCTP (RFC3436)
  * Failover and failback mechanisms
  * Diameter routing loops detection and avoidance
  * Base Accounting support is provided by the [wiki:app_acct.fdx] extension.
  * Messages '''relaying''' is natively supported by the daemon without need for any extension.
  * Diameter '''Redirects''' are supported by the [wiki:rt_redirect.fdx] and [wiki:app_redirect.fdx] extensions.
 * '''Diameter EAP server''' (RFC4072) support is provided by the [wiki:app_diameap.fdx] extension.
 * '''Diameter SIP''' (RFC4740) support is provided by the [wiki:app_sip.fdx] extension.
 * '''RADIUS/Diameter translation''' for NASREQ (RFC4005), EAP (RFC4072), and SIP (RFC4740) is provided by the [wiki:app_radgw.fdx] extension.

Since the implementation supports '''extensions''', it is quite easy to implement support for other Diameter applications or behavior (dynamic peer discovery, ...)
