Management and orchestration of network slices in 5G, fog, edge, and clouds

This chapter reviews the state-of-the-art literature on network slicing in 5G, edge/fog, and cloud computing. It identifies the spectrum challenges and obstacles that must be addressed to achieve the ultimate realization of the concept. The chapter provides a brief introduction of 5G, edge/fog, and clouds and their interplay. It outlines the 5G vision for network slicing and identifies a generic framework for 5G network slicing. The chapter reviews research and projects related to network slicing in cloud computing context, while focusing on software-defined networking (SDN) and network function virtualization (NFV) technologies. It explores network slicing advances in emerging fog and edge cloud computing, which leads us to identify the key unresolved challenges of network slicing within these platforms. The chapter discusses the gaps and trends toward the realization of network slicing vision in fog and edge and software-defined cloud computing.
