The NetroSphere concept was devised by NTT laboratories toguide the development of communication network technology forthe future. The aim is to provide customers and service providers
speed, with high reliability, and at low cost by adopting anarchitecture in which a diverse range of functions can be used
flexibly. This article outlines the aims of the NetroSphere concept and the network architecture that supports
these aims.

network elements (NEs) are deployed on NTT networks. We needorder to manage the different types of NEs. Consequently, the useof multiple EMSs increases the operating cost and the operator workload.
We are working to solve this problem by studying a unified EMS, which we call transport network
management (TM) platform technology, that can manage various kinds of network technologies. We present
the concept and core technologies of TM platform technology in this article.
