The Importance of Network Slicing and Optimization in Virtualized Cloud Radio Access Network

The rise of 5G mobile network and the increasing of the number of connected devices with the deployment of new technologies, make the operator thinking of using new network architecture to meet the requirement of such situation. Cloud Radio Access Network (C-RAN) is a network that become the infrastructure of next generation, with the new evolving technologies, such as Network Function Virtualization (NFV) and Software Defined Networking (SDN). Network slicing enables the orchestration of Radio Access Network (RAN) resources, by isolating the physical network to virtual slices each of them reserved for determined application or services. Besides, implementing optimization method on C-RAN infrastructure led to a large number of profit chances. This paper will explain in depth the importance of such technologies and methods in Virtualized C-RAN.
