Guidelines for Autonomic Service Agents
draft-carpenter-anima-asa-guidelines-02
Abstract
This document proposes guidelines for the design of Autonomic Service
Agents for autonomic networks. It is based on the Autonomic Network
Infrastructure outlined in the ANIMA reference model, making use of
the Autonomic Control Plane and the Generic Autonomic Signaling
Protocol.

1. Introduction
This document proposes guidelines for the design of Autonomic Service
Agents (ASAs) in the context of an Autonomic Network (AN) based on
the Autonomic Network Infrastructure (ANI) outlined in the ANIMA
reference model [I-D.ietf-anima-reference-model]. This
infrastructure makes use of the Autonomic Control Plane (ACP)
[I-D.ietf-anima-autonomic-control-plane] and the Generic Autonomic
Signaling Protocol (GRASP) [I-D.ietf-anima-grasp].
There is a considerable literature about autonomic agents with a
variety of proposals about how they should be characterized. Some
examples are [DeMola06], [Huebscher08], [Movahedi12] and [GANA13].
However, for the present document, the basic definitions and goals
for autonomic networking given in [RFC7575] apply . According to RFC
7575, an Autonomic Service Agent is "An agent implemented on an
autonomic node that implements an autonomic function, either in part
(in the case of a distributed function) or whole."
The reference model [I-D.ietf-anima-reference-model] expands this by
adding that an ASA is "a process that makes use of the features
