NFV and SDN Create New Requirements for Service Assurance, which Cannot be Fulfilled by Existing Software
"Service assurance systems must support services that are delivered across physical and virtual networks, provide unified virtual next-generation network monitoring, and underpin the closed-loop processes for automated assurance and orchestration."

This report discusses how service assurance solutions should evolve to address the new challenges presented by network virtualisation. It presents the key initial use cases that are being considered within the industry and are most likely to be implemented by communications service providers (CSPs) that are embarking on the virtualisation journey.

It also provides recommendations for vendors on how best to address the opportunities and challenges.

It is based on:
- research published in Analysys Mason’s Software-Controlled Networking and Network Orchestration programmes
- interviews with CSPs and vendors
- ETSI publications.

The introduction of network function virtualisation (NFV) and software-defined networking (SDN) will result in a new hybrid virtual next-generation network (vNGN) with co-existing physical and virtual network components, creating new service assurance requirements that existing software cannot easily fulfil.

This report:

- discusses why the existing service assurance OSS is not fit for purpose for NFV and SDN
- assesses the characteristics of new service assurance solutions
- explains why communications service providers (CSPs) need a hybrid approach to service assurance on vNGNs
- outlines the initial use cases that vendors and CSPs should address
- analyses the trials and proof-of-concept (PoC) demonstrations that are being undertaken.
