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.
NOTE: This course is not delivered with the FoldOut methodology.
