New Telco NFV Service and User Story
New Telco NFV Services
Network Function Virtualization (NFV) uses the technologies of IT virtualization to virtualize entire classes of network node functions into building blocks that may connect, or chain together, to create communication services. NFV relies upon, but differs from, traditional server-virtualization techniques, such as those used in enterprise IT. For example, NFV traffic is typically pass-through and high throughput so that VNF (Virtualized Network Function) can provide high performance networking function. On the other hand, in case of enterprise IT and cloud, networking is never a bottleneck, and interoperability and API stability is key to those SaaS and PaaS.
The key driver of NFV is the need from Telco Service Providers to accelerate the deployment of new network services to support their revenue and growth objectives.
Because of the objectives and driver of NFV which is different from traditional enterprise IT and cloud, Telco Service Providers has been providing various NFV platforms globally, for example, AT&T ECOMP, China Mobile NovoNet, etc., and related open source platform Open Networking Automation Platform (ONAP).
