Asynchronous Management Protocol Agent Application Data Model
draft-birrane-dtn-adm-agent-05
This document describes an Application Data Model (ADM) for an Asynchronous Management Protocol (AMP) Agent. The AMP Agent represents a managed device in the Asynchronous Management Architecture. This document is in compliance with the template provided by [I-D.birrane-dtn-adm].
This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.

An Application Data Model (ADM) provides a guaranteed interface for the management of an application or protocol in accordance with the Asynchronous Management Architecture (AMA) defined in [I-D.birrane-dtn-ama]. The ADM described in this document complies with the ADM Template provided in [I-D.birrane-dtn-adm] as encoded using the JSON syntax.
The AMP Agent ADM provides the set of information necessary to remotely manage agents in accordance with the Asynchronous Management Protocol (AMP) defined in [I-D.birrane-dtn-amp]. AMP provides a compact binary encoding of ADM objects and specifies a protocol for the exchange of those objects.
This ADM specifies those components of the Asynchronous Management Model (AMM) common to the management of any instance of any AMP Agent.
Any Manager software implementing this ADM MUST perform the responsibilities of an AMA Manager as outlined in [I-D.birrane-dtn-adm] as they relate to the objects included in this document.
Any Agent software implementing this ADM MUST perform the responsibilities of an AMA Agent as outlined in [I-D.birrane-dtn-adm] as they relate to the objects included in this document.
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.
The AMP Agent ADM's structure is in accordance to [I-D.birrane-dtn-adm]. This ADM contains metadata, table templates, and controls, variables, report templates, macros, edd, and operators. The contents of this ADM are derived from the main functions and data that an agent needs to run AMP [I-D.birrane-dtn-amp].
The Metadata that is present in this document is common to all ADMs. All ADMs have metadata that includes the name, namespace, and version of the ADM as well as the name of the organization that is issuing that particular ADM. This is important for identification purposes of the ADMs and to ensure version control.
Because there are calculations done in various ADM objects that are needed for AMP, the operators that were chosen were ones that were the most common. For each of the most common operators, the only ones that were expressed in the document were ones that had the same input types and result types. This is to prevent a long list of operators that may never be used. The additional information provided in this ADM dealt with the number of known variables, macros, rules, controls and constants as well as the number of those instances that were running.
This section outlines the namespaces used to uniquely identify ADM objects in this specification.
In accordance with [I-D.birrane-dtn-adm], every ADM is assigned a moderated Namespace. In accordance with [I-D.birrane-dtn-amp], these namespaces may be enumerated for compactness. The namespace and ADM identification for these objects is defined as follows.
| Identifier | Value |
|---|---|
| Namespace | Amp/Agent |
| ADM Enumeration | 1 |
Given the above ADM enumeration, in accordance with [I-D.birrane-dtn-amp], the following AMP nicknames are defined.
| Nickname | Collection |
|---|---|
| 20 | Amp/Agent/Const |
| 21 | Amp/Agent/Ctrl |
| 22 | Amp/Agent/Edd |
| 23 | Amp/Agent/Mac |
| 24 | Amp/Agent/Oper |
| 25 | Amp/Agent/Rptt |
| 27 | Amp/Agent/Tblt |
| 29 | Amp/Agent/Var |
| 30 | Amp/Agent/Mdat |
| 31-49 | Amp/Agent/Reserved |
