                Guidelines for Autonomic Service Agents
                draft-carpenter-anima-asa-guidelines-08

Abstract

   This document proposes guidelines for the design of Autonomic Service
   Agents for autonomic networks, as a contribution to describing an
   autonomic ecosystem.  It is based on the Autonomic Network
   Infrastructure outlined in the ANIMA reference model, using the
   Autonomic Control Plane and the Generic Autonomic Signaling Protocol.
