Japan Software-Defined Network 2015-2019 Forecast and 2014 Review: Datacenter/Carrier SDN and NFV
This IDC study analyzes the current trends and future prospects of the Japanese software-defined network (SDN) and network functions virtualization (NFV) markets. SDN in datacenters, enterprise networks, and carrier networks — as well as NFV in carrier networks — have all progressed from the conceptual and testing stages and are now in practical use, applied within commercial networks. Although datacenter SDN was the earliest SDN market to pick up and has made some progress in being implemented in commercial environments, it is starkly clear that there is a need to be able to control physical networks the way that now only virtual networks can be controlled, as well as that there is a need to face problems of SDN price structures. Through dialogs with customers, SDN within company networks is shifting to a more realistic approach as companies determine where best to deploy SDN technologies and what the actual effects of implementing them are.
Concerning the market targeting telecommunications carriers, starting in FY2015, Japanese telecoms are planning to deploy commercialized versions of virtualized evolved packet core (vEPC), making it clear what the route to the commercialization of NFV will be. "Adoption of NFV by carriers is inevitable. Telecom networking equipment vendors should actively contribute to the success of their customers' moves to the use of NFV and to the resulting reductions in CAPEX and OPEX and delivery of improved service competitiveness. They must actively endeavor to promote the adoption of NFV without fearing the consequences of reduced business in hardware," argues Kenichi Kusano, IDC Japan communications group manager.
