RFC 9390: Diameter Group Signaling
Proposed Standard- M. Jones
- M. Liebsch
- L. Morand
- April 2023
- IETF publication
- Operations and Management Area
Abstract
In large network deployments, a single Diameter node can support over a million concurrent Diameter sessions. In some use cases, Diameter nodes need to apply the same operation to a large group of Diameter sessions concurrently. The Diameter base protocol commands operate on a single session so these use cases can result in many thousands of command exchanges enforcing the same operation on each session in the group. In order to reduce signaling, it is desirable to enable bulk operations on all (or part of) the sessions managed by a Diameter node using a single or a few command exchanges. This document specifies the Diameter protocol extensions to achieve this signaling optimization.

RFC 8581: Diameter Agent Overload and the Peer Overload Report
Proposed Standard- S. Donovan
- August 2019
- IETF publication
- Operations and Management Area
Abstract
This specification documents an extension to the Diameter Overload Indication Conveyance (DOIC), a base solution for Diameter overload defined in RFC 7683. The extension defines the Peer Overload report type. The initial use case for the peer report is the handling of occurrences of overload of a Diameter Agent.

RFC 8582: Diameter Overload Rate Control
Proposed Standard- S. Donovan
- E. Noel
- August 2019
- IETF publication
- Operations and Management Area
Abstract
This specification documents an extension to the Diameter Overload Indication Conveyance (DOIC) base solution, which is defined in RFC 7683. This extension adds a new overload-control abatement algorithm. This abatement algorithm allows for a DOIC reporting node to specify a maximum rate at which a DOIC reacting node sends Diameter requests to the DOIC reporting node.

RFC 8583: Diameter Load Information Conveyance
Proposed Standard- B. Campbell
- S. Donovan
- JJ. Trottin
- August 2019
- IETF publication
- Operations and Management Area
Abstract
RFC 7068 describes requirements for Overload Control in Diameter. This includes a requirement to allow Diameter nodes to send "load" information, even when the node is not overloaded. The base solution defined in RFC 7683 (Diameter Overload Information Conveyance (DOIC)) describes a mechanism meeting most of the requirements but does not currently include the ability to send load information. This document defines a mechanism for the conveying of Diameter load information.

RFC 8506: Diameter Credit-Control Application
Proposed Standard- L. Bertz
- D. Dolson
- Y. Lifshitz
- March 2019
- IETF publication
- Operations and Management Area
Abstract
This document specifies a Diameter application that can be used to implement real-time credit-control for a variety of end-user services such as network access, Session Initiation Protocol (SIP) services, messaging services, and download services. The Diameter Credit- Control application as defined in this document obsoletes RFC 4006, and it must be supported by all new Diameter Credit-Control application implementations.
