Implementing OSI Network Management Facilities on the Xunet ATM Platform

We present the design of an OSI-based network management system for the Xunet ATM platform. We de ne a set of inheritance and containment trees and elaborate on the problem of linking logical objects in the Management Information Base with the corresponding network objects. Furthermore, we address several issues that are left open by the OSI management standards and require further consideration by the software developer, such as maintaining the consistency of logical objects, increasing the performance of the management agent, and recovering from failures. Finally, we identify the need for a more formal and precise model for network management that can take advantage of the many commonalities in the functionality of ATM networks to ensure portability between di erent platforms.
