Abstract: A network and network element combined view information model of Ethernet at interface between NMS (network management system) and EMS (element management system) is defined. The structure layer of Ethernet and the partitioning of Ethernet layer network based on VLAN (virtual local area network) are discussed with defining network view information model. The modeling of bridge functional entities is involved in the network element view information model. This model is applied in EPON(Ethernet passive optical networks) network management. In this application, the association mechanism between network view and network element view information is proposed. Besides, an interaction scenario of bandwidth assignment based on the information model is analyzed. The information model proposed here has been verified by a prototype management system. And the information model has also been accepted as ITU-T Recommendation Q.838.1.
