Abstract:

The management information modeling methods of connectionless network are studied based on the characteristic concept of connectionless network - flow. The contents involve the basic principles of information modeling of connectionless network, the transform mechanisms from functional architecture components to managed resources, and the principles to identify the relationships between managed resources，as well as essential attributes of those resources. The modeling methods proposed here focuses on the guidance for detailed steps during the modeling process. The characteristics of connectionless networks as well as the concept of flow are analyzed, and the management abstraction from functional architecture components to managed resources is dwelt on. The methods have been applied in the information modeling of Ethernet passive optical networks (EPON) network management interface, and the information model has already been accepted as ITU-T recommendation Q.838.1.

Key words: connectionless network, information modeling methods, management information model
