                  Asynchronous Management Architecture
                        draft-birrane-dtn-ama-05

Abstract

   This document describes an asynchronous management architecture (AMA)
   suitable for providing application-level network management services
   in a challenged networking environment.  Challenged networks are
   those that require fault protection, configuration, and performance
   reporting while unable to provide humans-in-the-loop with synchronous
   feedback or otherwise preserve transport-layer sessions.  In such a
   context, networks must exhibit behavior that is both determinable and
   autonomous while maintaining compatibility with existing network
   management protocols and operational concepts.
