TMN-BASED CUSTOMER NETWORK MANAGEMENT FOR ATM NETWORKS

Effective end-to-end management of today's globalized heterogeneous co rporate customer networks, a mixture of ATM WANs and ATM LANs, is esse ntial for customers at the cutting edge of technology. ATM WAN and ATM LAN management systems generally have different management policies a nd management information models. Studies on the customer network mana gement system (CNMS) to realize end-to-end customer network management have thus adopted the telecommunications management network (TMN) int eroperability concept, which is based on CNM manager and agent interop eration. This article proposes an end-to-end customer network manageme nt method that realizes interoperation. in order to realize configurat ion management, fault management, and performance management, the CNM agent extracts the information needed by CNMS from the ATM transport n etwork operations system and controls the operations system accordingl y.
