Internet Network Resource Information Model

The foundation of any network management systems is a database that contains information about the network resources relevant to the management tasks. A network information model is an abstraction of network resources, including both managed resources and managing resources. In the SNMP-based management framework, management information is defined almost exclusively from a “device” viewpoint, namely, managing a network is equivalent to managing a collection of individual nodes. Aiming at making use of recent advances in distributed computing and in object-oriented analysis and design, the Internet management architecture can also be based on the Open Distributed Processing Reference Model (RM-ODP). The purpose of this article is to provide an Internet Network Resource Information Model. First, a layered management information architecture will be discussed. Then the Internet network resource information model is presented. The information model is specified using Object-Z.
