LAN/WAN management integration using ATM CNM interface
Miyoshi Hanaki, T. Araki, Hiroshi Yamamoto, T. Yamamura · 2002
In an integrated network of ATM-LANs and ATM-WANs, both public and private networks that belong to different management domains with different management policies are used for communication between end systems. Although network management that covers end-to-end communication over the whole integrated network is needed, it is difficult to manage the configuration, know the status of communication connection, and handle the provisioning at the total network level. Moreover, it is not easy to isolate faults and monitor performance among the heterogeneous networks. We propose a cooperative end-to-end management method that makes good use of CNM (customer network management) services of ATM-WAN, and combines them with ATM-LAN management services. Our proposal includes: (1) end-to-end management based on the network partitioning concept, (2) ATM-WAN abstraction and modeling from the viewpoint of ATM-LAN customers at the network level, and (3) a couple of new managed objects for CNM services.
