NEC Corporation has announced that they have developed dynamic optimal path management technologies. The new technologies are for mobile and fixed networks, and use OpenFlow.      

The technologies pick up the most suitable communication route. They also switch between heterogeneous communication methods to conserve energy. NEC has developed prototype Programmable Flow switch. The company has also carried out a trial session between Japan and the US.  

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 in response to congestion and environmental conditions makes it possible to continually provide end users with high quality service.

2. Electric power-saving of mobile backhaul

Electricity can be conserved by condensing network paths during nighttime hours, when communication traffic is low, and turning off the power for excess transfer stations.
