Today's enterprise information systems are modeled on the client/server paradigm over LANs interconnected by WANs, but it involves problems of network management costs and complicated management jobs. So efficient network management is strongly required for LANs interconnected by WANs. In this paper, we describe a hierarchical enterprise network management system for LANs interconnected by WANs, based upon analysis of LAN management operations. This network management system has a hierarchical model with three levels, i.e., center level, area level, and user-site level. We also describe how this system was implemented as a nation-wide corporate network with many LAN sites, emphasizing on its functional structure. This network's success has confirmed usefulness of the management system.
