Abstract
This document describes an architecture for describing 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.
