Transmuting Legacy Network Management Environment into TMN-based Integrated Network Management

Today, TMN becomes world-wide concept for network management of public network. Furthermore, it is no doubt that TMN will be the most general network management technology in the next millennium. If TMN-based network management is introduced in public network of Latin America, the integration of the legacy networks into TMN must be accompanied. The topic of our paper is considering for legacy network, one of the important problem in building TMN-based network management infrastructure. The most important consideration for legacy network is method adapting legacy management interface to TMN Q interface. Though there are some adaptation methods such as Q-adapter and Q-addition, nobody can decide which adaptation method is better. We have developed TMN-based network management system for legacy ATM switching node since 1995 and have much technical experience for reality of TMN. In this paper, we present significant problems for introducing TMN in legacy public network and propose methods to solve the problems with our experience for TMN.
