A design method of TMN-DCN topology for integrated management of vario
us networks is presented and an example is shown. The TMN-DCN devices
are assigned for each of the various networks. These devices have func
tions of network management. For a very large network, several TMN-DCN
devices are assigned. As a next step, TMN-DCN topology design using t
he TMN-DCN devices as nodes of TMN-DCN has to be carried out.
