The design and implementation of a high performance management information tree for a TMN platform

In telecommunication management network (TMN) systems, a managed object (MO) is an OSI abstract view of a logical or physical system resource to be managed. Instances of MO classes can be thought as logically containing other instances. The full set of MO instances available across a management interface are organized in a management information tree (MIT). Managed objects in an MIT may be accessed either individually or collectively through an object-oriented query facility. The speed of MO selection operation highly affects the overall performance of the network management system. In this paper, we propose an MIT mechanism to reduce the MO selection time. This MIT consists of three kinds of nodes: MO node, MO class node and MO info node. A class level filtering (CLF) mechanism is developed based on the MIT to avoid unnecessary filtering time. After detailed provisions on this MIT, some evaluation results are given, and these results are checked against existing MIT.
