INTEGRATED NETWORK MANAGEMENT SYSTEM FOR LARGE-SCALE COMPLEX NETWORKS.

Almost all conventional information network management systems have been developed as sole use systems designed to manage such subnetworks as a modem subnetwork, a PBX subnetwork, or a computer/terminal subnetwork. For a relatively small-scale network, an independent network management system for each subnetwork is sufficient. For a complicated large-scale network, however, an integrated management system is required to attain easier operability, improved network reliability and lower administrative costs. The Computer and Communications Network Management System (C&C-NMS) was developed as an integrated network management system, capable of performing integrated and unified management for all subnetworks. The software structure and protocol in this system are based on NEC's Distributed Information Network Architecture for Extended Environment 'DINA-XE', which is in accordance with ISO Open Systems Interconnection (OSI) standards. This enables the C&C-NMS to be open-ended, meeting the requirements for use in a multi-vendor environment.
