Abstract

Software-Defined Network (SDN) empowers the evolution of Internet with the OpenFlow, Network Virtualization and Service Slicing strategies. With the fast increasing requirements of Mobile Internet services, the Internet and Mobile Networks go to the convergence. Mobile Networks can also get benefits from the SDN evolution to fulfill the 5th Generation (5G) capacity booming. The article implements SDN into Frameless Network Architecture (FNA) for 5G Mobile Network evolution with proposed Mobile-oriented OpenFlow Protocol (MOFP). The Control Plane/User Plane (CP/UP) separation and adaptation strategy is proposed to support the User-Centric scenario in FNA. The traditional Base Station is separated with Central Processing Entity (CPE) and Antenna Element (AE) to perform the OpenFlow and Network Virtualization. The AEs are released as new resources for serving users. The mobile-oriented Service Slicing with different Quality of Service (QoS) classification is proposed and Resource Pooling based Virtualized Radio Resource Management (VRRM) is optimized for the Service Slicing strategy with resource-limited feature in Mobile Networks. The capacity gains are provided to show the merits of SDN based FNA. And the MiniNet based Trial Network with Service Slicing is implemented with experimental results.
