CONTENTS
While still keeping the big picture and real-world use cases in view, it describes the three main sub-components of MANO (NFVO, VNFM and VIM) and explains how they are used to construct a Network Service (NS) comprising virtualized as well as physical network functions (VNFs and PNFs) connected with virtual network links (VLs).
This course exists in a shorter version, MANO in an Hour, and a full-length version covering all topics in much more detail.
PREREQUISITES
Working knowledge of computer and telecommunications systems as well as understanding of the ETSI NFV architecture corresponding to the course “Network Function Virtualization – Architecture and Principles”.
