A MD can further reconstitute or impose structure on this interface so that it matches the OS application's expected format. The NMF API offers a standardized, object-oriented API for telecommunications management applications. The architecture comprises three modular, layered APIs. Prior to the NMF API, there were already some widely accepted standard APIs for TMN applications. This reduces time to market, lowers development costs, and shortens the learning curve for a development team.
Specific applications implement a static information model.
Generic applications provide for changing management information and dynamically interpret network changes into the information model. Development efforts do not need to restrict functionality or to impose unnecessary limitations based on some subset of the information model. TMN Framework 2. The TMN Functional Model 3.
