Features

The freeDiameter implementation supports the following features:

• Full support for the Diameter Base Protocol defined in RFC3588 and ​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 app_acct.fdx extension.
• Diameter EAP server (RFC4072) support is provided by the app_diameap.fdx extension.
• Diameter SIP (RFC4740) support is provided by the app_sip.fdx extension.
• RADIUS/Diameter translation for NASREQ (RFC4005), EAP (RFC4072), and SIP (RFC4740) is provided by the 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, ...)
