Service assurance is a critical part of operationalizing NFV/SDN-based networks

Anil Rao, Senior Analyst, Analysys Mason

The industry is gradually moving towards operationalizing NFV and SDN networks. In this report, Anil Rao addresses current ongoing industry initiatives and how current approaches to service assurance are unsuitable to support the future mode of operations.

"CSPs are actively engaged in developing operational architectures for network functions virtualization/software-defined networking (NFV/SDN). While NFV management and network orchestration (MANO) has received most attention to date, other important functions such as service design and service assurance (SA) are now coming to the fore. This research note discusses the characteristics of the new SA and why it will be a crucial component in operationalizing NFV/SDN."
