                Guidelines for Autonomic Service Agents
                draft-carpenter-anima-asa-guidelines-06

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.
