NTT outlined its work developing the “NetroSphere concept” — a new way build carrier network infrastructure that differs from other NFV approaches by taking the decoupled software/hardware paradigm all the way down to the component level.
NTT said its approach promises enhanced flexibility and elasticity while also drastically reducing costs. Breaking up the functions of conventional large-scale equipment into modules will enable a greater diversity of suppliers to participate in the market and hence widen the selection of available products.
Instead of using conventional purpose-built high-functionality equipment, NetroSphere aims to divide them into small modular components, and flexibly assemble those components at will. NetroSphere will not limited to decoupling software components from equipment. It pursues modularization as much as possible, ultimately at the sub-device level such as the CPU and memory. These modules will be distributed in locations that are optimal for each type of them, and prepared to be used as resource pool. Then, they will be virtually assembled to form a virtual system to provide required functions.
There are two components to the NetroSpher concept: (1) Multi-Service Fabric (MSF), an architectural design of carrier network in which functions are achieved using simple general-purpose servers and switches, and (2) New Server Architecture (MAGONIA).
NTT plans to open its work on “MAGONIA” and “Multi-Service Fabric (MSF)” to other carriers and vendors.
