Information Architecture

TMN's information architecture uses an object oriented approach and is based on OSI's Management Information Model [7]. According to this model, the management view of a managed object is visible at the managed object boundary. At this boundary, the management view is described in terms of (Figure 18):

• Attributes, which are the properties or characteristics of the object.
• Operations, which are performed upon the object.
• Behaviour, which is exhibited in response to operations.
• Notifications, which are emitted by the object.

The managed objects reside within managed systems, which include agent functions to communicate with the manager. TMN uses the same manager-agent concept as OSI.

Because TMN's information architecture is a copy from OSI's information architecture, this tutorial will not discus the information architecture any further.
