NEC Corp. has dynamic optimal path management technologies for mobile and fixed networks using OpenFlow, one of the future Internet technologies. These new technologies, including modules that observe the utilization status of multiple base stations for each mobile communication method, dynamically select the most suitable mobile communication routes by analyzing location information within mobile networks, received signal power level, communication resource utilization and mobile backhaul congestion.
OpenFlow is a general term for both technologies and interfaces proposed by the OpenFlow consortium led by Stanford University. This technology provides more precise network controls, such as routing and service quality controls, for network flow where “flow” is a unit of measurement and control of network communications. NEC joined this consortium upon its establishment.
The technologies also provide high quality services by dynamically switching between heterogeneous mobile communications methods and improve energy conservation by switching off low communication load base stations for mobile backhaul networks, including base stations, network lines, switches and servers.
NEC has already developed a prototype of Programmable Flow switch and completed a trial between Japan and the United States. Furthermore, NEC jointly established the Clean State Laboratory with Stanford University and is conducting advanced research and development for the implementation of a global structure for Future Internet services.
These developments also provide a core technology using OpenFlow that enables efficient and flexible network management of mobile networks, which are constantly gaining speed and bandwidth.
Adoption of these technologies resolves the following issues:
1. Dynamic switching between multiple mobile communication methods
2. Electric power-saving of mobile backhaul
The above technologies each contribute to the ability of mobile communications carriers to reduce operational management costs and create new services.
