The D-NFV modules add to Megaplex-4 a built-in standard Intel x86 core that hosts virtual machines providing virtual network functions (VFs) or value-added service capabilities. This new capability provides a quick and easy way to introduce new services and applications with the benefit of function localization at the customer premises. For U&T the modules provide a way to implement new functionalities and applications into the multiservice platform and to integrate OT and IT equipment into one chassis. They also provide an easy way to cope with new regulatory requirements (such as NERC-CIP).
