Protocol that provides an Authentication, Authorization, and Accounting (AAA) framework for applications such as network access or IP mobility. Diameter works in both local and roaming AAA situations. Diameter can also be used as a signaling protocol for mobility management which is typically associated with an IMS or wireless type of environment.
Diameter Agent
A Diameter node that provides relay, proxy, redirect, or translation services.
Diameter Agent Message Processor
A computer or blade that is hosting the DSR. Multiple instances of the DSR each execute on a separate physical DA-MP. Each instance shares run-time status information with all other instances for the Diameter connections that it controls. In inter-MP routing, an instance can route an ingress Answer message to another instance that performed routing for the corresponding ingress Request message. See DA-MP.
Diameter Application
A Diameter Application is not a software application, but a protocol based on the Diameter base protocol. Each Diameter Application is defined by an Application Identifier and can add new Command Codes and new mandatory AVPs. Adding a new optional AVP does not require a new Application.
Diameter Application Layer

An Elastic Charging Engine (ECE) component that serves as the Online Charging System (OCS) front-end server for the BRM system. It processes network requests for Gy, Sy, and Sh Diameter interfaces, acts as a Diameter Server, and presents the BRM ECE to the network as a Diameter Credit-Control Application. Diameter Gateway also translates Diameter requests received from Diameter Clients (for example, Application Servers, Policy Servers or IMS-GWFs) into ECE Java API requests. It translates the response from the Elastic Charging Server back into Diameter requests and responds back to the requesting Diameter Client.
Diameter Network
A set of Diameter Nodes identified by a Realm name. A Diameter Node that initiates a Diameter message is identified by the mandatory Origin-Realm AVP in the message. A Diameter Node that is the intended destination of a Diameter message is identified by the mandatory Destination-Realm AVP in the message.
Diameter Node
A host process that implements the Diameter protocol, and acts either as a client, agent or server.
Diameter Payload Octets
Number of octets in a Diameter message including the Diameter fixed header and all Diameter AVPs
Diameter Relay Agent
Diameter agent that forwards requests and responses to other Diameter nodes based on routing-related AVPs (for example, Destination-Realm) and routing table entries. Since relays do not make policy decisions, they do not examine or alter non-routing AVPs. As a result, relays never originate messages, do not need to understand the semantics of messages or non-routing AVPs, and are capable of handling any Diameter application or message type.

Device-Watchdog-Answer
A Diameter message used with the Device-Watchdog-Request (DWR) message to proactively detect connection failures. If no traffic is detected on a connection between the Mobile Originated application and the prepaid rating engine within the configured timeout period, a DWR message is sent to the prepaid rating engine. If the prepaid rating engine fails to respond with a DWA within the required time, the connection is closed with the prepaid rating engine and initiates failover procedures. All new and pending requests are then sent to the secondary server.
DWR

A Diameter message used with the Device-Watchdog-Answer (DWA) message to proactively detect connection failures. If no traffic is detected on a connection between the Mobile Originated application and the Diameter server within the configured timeout period, a DWR message is sent to the Diameter Server. If the Diameter server fails to respond within the required time, the connection is closed with the Diameter server and initiates failover procedures. All new and pending requests are then sent to the secondary Diameter server.
