NFV MANO in an Hour

CONTENTS

This course uses as a starting point the main ETSI NFV architecture with its building blocks, and then focuses its attention on the Management and Orchestration (MANO) functions. 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 longer version, NFV MANO In Half a Day, and a full-length version covering all topics in much more detail.

PREREQUISITES
