Network Functions Virtualization (NFV) and Software Defined Networks (SDN) are an accepted evolution in all areas of network concepts and technologies. They are expected to further radically and dramatically transform not only telecommunication networks, campus, enterprise and datacenter networks, but accelerate the introduction of smart cities/homes/cars/businesses and green infrastructures. Currently, NFV and SDN are in the transition phase from development into first trials, evaluation and early deployments, too. A major impact for the rapid adoption is the shift to openness and knowledge exchange during the transition process. Open source software and hardware development, the convergence of IT and Telco development and alignment of operation processes as well as integration of latest research results in algorithms, hardware design, etc. together with a continuous competition of the best ideas for acceptance in the community has supported the widespread acceptance of NFV and SDN.

The special issue of journal will be consist of new approaches as well as dedicated work on missing aspects for improvements of NFV and SDN enabling architectures, algorithms, frameworks and operation of virtualized network functions and infrastructures.
