Effective end-to-end management of today's globalized heterogeneous corporate customer networks, a mixture of ATM WANs and ATM LANs, is essential for customers at the cutting edge of technology. ATM WAN and ATM LAN management systems generally have different management policies and management information models. Studies on the customer network management system (CNMS) to realize end-to-end customer network management have thus adopted the telecommunications management network (TMN) interoperability concept, which is based on CNM manager and agent interoperation. This article proposes an end-to-end customer network management method that realizes interoperation. In order to realize configuration management, fault management, and performance management, the CNM agent extracts the information needed by CNMS from the ATM transport network operations system and controls the operations system accordingly.
