The rapid evolution of the telecommunications industry has resulted in the
convergence of voice and data transport over a myriad of diverse architectu
res and technological domains. To overcome the problems that inevitably acc
ompany such a heterogeneous environment, Lucent Technologies is developing
a phased inter-domain network management solution. The new system architect
ure will enable service providers to integrate the diverse technologies of
multiple vendors, rendering transparent any differences among the heterogen
eous network equipment. This paper presents an overview of the proposed Inf
er-Domain Management System architecture being developed by Lucent's Commun
ications Software Group.
