10.1 Introduction
This chapter provides an insight into network management and orchestration in the 5th generation (5G), in particular highlighting how software‐defined networking (SDN) and network function virtualization (NFV) will enable increased agility, scalability, and faster time‐to‐market of 5G communication networks.
SDN proposes the decoupling of both the control plane (CP) and user plane (UP), which are commonly integrated nowadays in the network elements (NEs), by logically centralizing the control while leaving the NEs to forward traffic and apply policies according to instructions received from the control side. This permits the network to become programmable in a way that facilitates more flexibility than traditional networks. On the other hand, NFV enables the dynamic instantiation of network functions (NFs) on top of commodity hardware, permitting the separation of the current vertical approach. This vertical approach consists of deploying integrated functional software and hardware ...
