Avoiding uncharted , high impact problems ...
Deploying NFV without proper attention to the service life cycle promises catastrophic implications for service providers . Justin Paul ,
Head of OSS and NFV Marketing at Amdocs explains
The impact of software defined networking ( SDN ) and the network functions virtualisation ( NFV ) capability it has spawned , has had a considerable impact on the operational support of business dependent ICT systems . These technologies are forcing a rapid evolution of operational support systems ( OSS ) and producing realtime dynamic systems that are designed to support these flexible , businesses centred , high function , and rapidly changing networks . If the OSS systems of today are not enhanced or augmented in some way , they will not meet the needs of the networks in the future . Let me be clear : the failure to ' operationalise ' SDN and NFV will have a huge impact on the ability of service providers to monetise these technologies and in turn unlock the significant benefits that they promise .
The use of NFV and SDN can help to create highly dynamic networks that are potentially in a constant state of flux because those networks will dynamically reconfigure or change their way of working in a direct and automated response to given external parameters . This radically different ability is one of the driving catalysts for the evolution of OSS . As NFV / SDN achieves widespread adoption within the network , the increasingly dynamic nature of the network means that operational systems will need to adapt and change if they are to be able to respond to and support that critical operational change .
Existing OSS systems are clearly designed to be able to manage network changes : as new technologies are rolled out , maintenance programmes and upgrades are deployed in response , but they were never designed for networks that
