Underlying Principles of the OSI Reference Model
- Minimize the number of layers thus simplifying the tasks of describing
and integrating different layers.
- Establish boundaries at points where the description of services is
small and the number of interactions is minimum.
- Create layers that include different functions.
- Establish boundaries where history demonstrates that the implementation
can be partitioned.
- Engineer layers so that they can could be redesigned to take advantage
of new technology without changing the services and interfaces of adjacent
- Allow for the bypassing of sublayers.
- Each layer should add value
