Asynchronous Management Architecture
draft-ietf-dtn-ama-00
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.
