Challenges and Experiences in Transitioning Management Instrumentation from Command-Oriented to Model-Driven - Advances in Network-Embedded Management and Applications - page 5

model-driven architecture utilize a loosely coupled common abstract interface
to access feature

instrumentation.

Fig. 1. Command-oriented architecture showing management interfaces directly
manipulating feature data and services. Highlighted is the duplication and coverage
between management interfaces. The CLI showing complete coverage, while others
less
so.

Fig. 2. Illustrates how the model-driven architecture abstracts access to
instrumentation data and services through a common interface and normalizes data
and services availability to all management interfaces. Models in the upper layer
describe the management interfaces, while the models in the lower layer provide
definitions of the instrumentation they manage. Together, these models describe the
management instrumentation of the system in an end-to-end manner.
The general architecture of model-driven instrumentation has five primary
