Implementation of the TMN to a highly reliable distributed switching node

In this paper, we first select the TMN protocol structures so as to minimize the command response time. To ensure the efficient operation and design flexibility of the operation, administration and maintenance (OA&M) software, we propose a command-message handling function for mapping between managed objects (MOs) and the OA&M software. We also design MO classes for switching-system-specific devices with a redundant configuration that ensures operation of a highly reliable system. We confirmed the feasibility of the proposed techniques by constructing a prototype system
