NFV too Risky? Pursue Network Virtualization First - How Five Independent Platforms meet 16 Operator Requirements Today

Report Summary:

Telco Cloud Operators risk failure in Network Function Virtualization (NFV) unless they incorporate the capabilities of proven legacy networking platforms that go well beyond the limited centralized architecture of Data Center Cloud virtualization. Google and Amazon are insufficient models for network-wide virtualization.

Unless Telecommunications providers look beyond the hierarchical ‘terminal to host’ model of the Internet they will be taking huge risks in their NFV network implementations.

Roadmap to NFV demands both New Processes and New Products.

To manage the risky NFV evolution, operators should first leverage currently available high performance virtualized networking platforms as they hone their operations.

This report offers a checklist of requirements for operators to compare network platforms; and highlights five independent platforms that meet relevant criteria for scalable distributed network functionality. We summarize platforms from Hitachi-CTA, NetNumber, Openwave Mobility and Radisys that meet real network virtualization requirements today.
