As the operators’ management networks

Data Communication Networks（DCN）carry large amount of traffic information concerning Operation

Administration and Maintenance（OAM）.Therefore

it is necessary for the operators to safely

efficiently and reliably manage and monitor such networks.From the perspective of Network Management（NM）design

this paper uses topology calculation and display as well as the topological link auto-discovery functions to implement the smart management of DCN topology and offer user-friendly graphical interfaces

thus satisfying their need for the real-time monitoring and effective management of DCN.
