Guidelines for Autonomic Service Agents
draft-carpenter-anima-asa-guidelines-07
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.
