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, NFV MANO In Half a Day, and a much shorter version if time is of the essence.
NOTE: The course is under development and the content may be subject to changes.
