Mediation Functions

The Mediation Function (MF) block is located within the TMN and acts on information passing between NEFs or QAFs, and OSFs. A MF block can be used to connect a single (Figure 10), as well as multiple NEFs and QAFs to an OSF. MF blocks can also be cascaded.

Among the types of MFs that can be recognized, are those that:

• Augment OSFs; examples are storage and filtering of management information.
• Augment NEFs; an example is the transformation from the local representation of management information into a standardized form.
