An efficient integrated network management for heterogeneous LANs and WANs

Recently, high-speed local area networks (LANs) and wide area networks (WANs) have been employed in various areas to support multimedia communication services. Accordingly, integrated network management systems are necessary for the efficient maintenance of these communication networks. This paper proposes an integrated network management architecture that can simultaneously manage both LANs and WANs with either a standard or a proprietary network management protocol. The features of the proposed architecture are analyzed in comparison with a manager-of-managers architecture and a common platform architecture. In addition, an integrated network management system is designed and implemented that can simultaneously maintain both LANs and WANs.
