Review Changes to business modelsChanges to business models means shifting from a standardized supply service model where carriers provide services through individual networks such as NGN (Next Generation Network), to a B2B2X (business-to-business-to-X) business model where middle B operators can build businesses and services according to their needs by freely incorporating original value-added functions to the base functions supplied by the carriers.Accommodating these changes requires networks that can respond flexibly to various middle B operator needs and that can promptly offer services.The technology to achieve this is network abstraction technology. Unpredictable traffic changesNetwork traffic up to now has been uniform and predictable, as service traffic has been dominated by services provided by carriers, for example, phone, Internet, and video services.However, in the Netro-Sphere era, we envisage an increase in the unpredictability of traffic changes.This may be caused by various elements such as rapid changes to traffic flow due to the start of new services from middle B operators with the previously mentioned business model
