Descripción
SoftAir is a new wireless software-defined architecture with network function virtualization (NFV) solutions for 5G wireless systems. The concept of SDN has been proposed to efficiently create centralized network abstraction with the provisioning of programmability over the entire network. Moreover, the complementary concept of NFV has been further proposed to effectively separate the abstraction of functionalities from the hardware, such as decoupling the data forwarding plane from the control plane.
