A mathematical model of the whole network traffic optimization was established, and HDCA algorithm was designed in terms of the mathematical model's hierarchies.

Software-defined networks will provide some of this flexibility by separating the control function from data forwarding, but there are additional capabilities emerging, he says, such as intelligent switching of wavelengths, the ability to mix dedicated bandwidth with best-efforts networks, and application layer network traffic optimization, e.g.

The big idea: putting sensors everywhere that communicate in a mesh network and allow real-time tracking and optimization of everything from traffic to the power grid to the water supply.
