The report begins with a look at the effect of virtualization on operations support systems (OSS); then, drills down into network inventory, where we analyze how physical, logical and virtual views of the network and its services must come together to support emerging architectures. We note the extraordinary level of OSS transformations currently underwaysome with the impetus of virtualization, and some without. Back office systems need to automate and become more agile, regardless of the type of network they support. Because virtualization for the network infrastructure is driven by the CSP and supplier members within the European Telecommunications Standards Institutes (ETSI) Industry Specification Group for NFV, this report drills down to the perspective of MANOthe management and orchestration working group within ETSI. MANO is defining the future of management and support in the Network Functions Virtualization (NFV) environment. Next, the report explores the concept of inventory as one part of a bigger process that coordinates network information from multiple sources; and how that affects what has historically been known as the database of record. Lastly, Stratecast examines the varied approaches that leading network inventory suppliers are taking to ensure that inventory, and the OSS it drives, can continue to play an important role in the new networks.
