+1.  Introduction
+
+   Capabilities exchange is an important component of the Diameter base
+   protocol [RFC6733], allowing peers to exchange identities and
+   Diameter capabilities (protocol version number, supported Diameter
+   applications, security mechanisms, etc.).  As defined in RFC 3588,
+   however, the capabilities exchange process takes place only once, at
+   the inception of a transport connection between a given pair of
+   peers.  Therefore, if a peer's capabilities change (due to a software
+   update, for example), the existing connection(s) must be torn down
+   (along with all of the associated user sessions) and restarted before
+   the modified capabilities can be advertised.
+
+   This document defines a new Diameter application intended to allow
+   the dynamic update of a subset of Diameter peer capabilities over an
+   existing connection.  Because the Capabilities Update application
+   specified herein operates over an existing transport connection,
+   modification of certain capabilities is prohibited.  Specifically,
+   modifying the security mechanism in use is not allowed; if the
+   security method used between a pair of peers is changed, the affected
+   connection MUST be restarted.
+
+2.  Specification of Requirements
+
+   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
+   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
+   document are to be interpreted as described in RFC 2119 [RFC2119].

+
+
+3.  Diameter Protocol Considerations
+
+   This section details the relationship of the Diameter Capabilities
+   Update application to the Diameter base protocol.
+
+   This document specifies Diameter Application-Id 10.  Diameter nodes
+   conforming to this specification MUST advertise support by including
+   the value 10 in the Auth-Application-Id of the Capabilities-Exchange-
+   Request (CER) and Capabilities-Exchange-Answer (CEA) commands
+   [RFC6733].
+
+4.  Capabilities Update
+
+   When the capabilities of a Diameter node conforming to this
+   specification change, the node MUST notify all of the nodes with
+   which it has an open transport connection and which have also
+   advertised support for the Capabilities Update application using the
+   Capabilities-Update-Request (CUR) message (Section 4.1.1).  This
+   message allows the update of a peer's capabilities (supported
+   Diameter applications, etc.).
+
+   A Diameter node only issues a given command to those peers that have
+   advertised support for the Diameter application that defines the
+   command; a Diameter node must cache the supported applications in
+   order to ensure that unrecognized commands and/or Attribute-Value
+   Pairs (AVPs) are not unnecessarily sent to a peer.
+
+   The receiver of the CUR MUST determine common applications by
+   computing the intersection of its own set of supported Application
+   Ids against all of the Application-Id AVPs (Auth-Application-Id,
+   Acct-Application-Id, and Vendor-Specific-Application-Id) present in
+   the CUR.  The value of the Vendor-Id AVP in the Vendor-Specific-
+   Application-Id MUST NOT be used during computation.
+
+   If the receiver of a CUR does not have any applications in common
+   with the sender, then it MUST return a Capabilities-Update-Answer
+   (CUA) (Section 4.1.2) with the Result-Code AVP set to
+   DIAMETER_NO_COMMON_APPLICATION [RFC6733], and it SHOULD disconnect
+   the transport-layer connection.  However, if active sessions are
+   using the connection, peers MAY delay disconnection until the
+   sessions can be redirected or gracefully terminated.  Note that
+   receiving a CUA from a peer advertising itself as a relay (see
+   [RFC6733], Section 2.4) MUST be interpreted as having common
+   applications with the peer.
+
+   As for CER/CEA messages, the CUR and CUA messages MUST NOT be
+   proxied, redirected, or relayed.
+

+RFC 6737              Diameter Capabilities Update          October 2012
+
+
+   Even though the CUR/CUA messages cannot be proxied, it is still
+   possible for an upstream agent to receive a message for which there
+   are no peers available to handle the application that corresponds to
+   the Command Code.  This could happen if, for example, the peers are
+   too busy or down.  In such instances, the 'E' bit MUST be set in the
+   answer message with the Result-Code AVP set to
+   DIAMETER_UNABLE_TO_DELIVER to inform the downstream peer to take
+   action (e.g., re-routing requests to an alternate peer).
+
+4.1.  Command Code Values
+
+   This section defines Command Code [RFC6733] values that MUST be
+   supported by all Diameter implementations conforming to this
+   specification.  The following Command Codes are defined in this
+   document: Capabilities-Update-Request (CUR, Section 4.1.1), and
+   Capabilities-Update-Answer (CUA, Section 4.1.2).  The Diameter
+   Command Code Format (CCF) ([RFC6733], Section 3.2) is used in the
+   definitions.
+
+4.1.1.  Capabilities-Update-Request
+
+   The Capabilities-Update-Request (CUR), indicated by the Command Code
+   set to 328 and the Command Flags' 'R' bit set, is sent to update
+   local capabilities.  Upon detection of a transport failure, this
+   message MUST NOT be sent to an alternate peer.
+
+   When Diameter is run over the Stream Control Transmission Protocol
+   (SCTP) [RFC4960], which allows connections to span multiple
+   interfaces and multiple IP addresses, the Capabilities-Update-Request
+   message MUST contain one Host-IP-Address AVP for each potential IP
+   address that may be locally used when transmitting Diameter messages.
+
+   Message Format
+
+      <CUR> ::= < Diameter Header: 328, REQ >
+                { Origin-Host }
+                { Origin-Realm }
+             1* { Host-IP-Address }
+                { Vendor-Id }
+                { Product-Name }
+                [ Origin-State-Id ]
+              * [ Supported-Vendor-Id ]
+              * [ Auth-Application-Id ]
+              * [ Acct-Application-Id ]
+              * [ Vendor-Specific-Application-Id ]
+                [ Firmware-Revision ]
+              * [ AVP ]

+RFC 6737              Diameter Capabilities Update          October 2012
+
+
+4.1.2.  Capabilities-Update-Answer
+
+   The Capabilities-Update-Answer, indicated by the Command Code set to
+   328 and the Command Flags' 'R' bit cleared, is sent in response to a
+   CUR message.
+
+                     Message Format
+
+                     <CUA> ::= < Diameter Header: 328 >
+                               { Origin-Host }
+                               { Origin-Realm }
+                               { Result-Code }
+                               [ Error-Message ]
+                             * [ AVP ]
+
+5.  Security Considerations
+
+   The security considerations applicable to the Diameter base protocol
+   [RFC6733] are also applicable to this document.
+
+6.  IANA Considerations
+
+   This section explains the criteria to be used by the IANA for
+   assignment of numbers within namespaces used within this document.
+
+6.1.  Application Identifier
+
+   This specification assigns the value 10 (Diameter Capabilities
+   Update) from the Application Identifiers namespace [RFC6733].  See
+   Section 3 for the assignment of the namespace in this specification.
+
+6.2.  Command Codes
+
+   This specification assigns the value 328 (Capabilities-Update-
+   Request/Capabilities-Update-Answer (CUR/CUA)) from the Command Codes
+   namespace [RFC6733].  See Section 4.1 for the assignment of the
+   namespace in this specification.
+
+7.  Contributors
+
