Abstract
This document describes an architecture for describing Simple Network
Management Protocol (SNMP) Management Frameworks. The architecture
is designed to be modular to allow the evolution of the SNMP protocol
standards over time. The major portions of the architecture are an
SNMP engine containing a Message Processing Subsystem, a Security
Subsystem and an Access Control Subsystem, and possibly multiple SNMP
applications which provide specific functional processing of
management data. This document obsoletes RFC 2571.
