The original approach to NFV advocated Distributed NFV (D-NFV), to enable the placement of virtualized network functions (VNFs) throughout the network, where they are most effective and least expensive. VNFs may be located in data centers, network nodes and at the customer premises.

RAD addresses the D-NFV approach with novel solutions that integrate an x86 platform for VNF hosting into a L2/L3 NID controlled by the service provider. This solution converges the control of conventional network elements, VNFs and IT applications, optionally by using SDN principles.

Running VNFs at the customer site is justified in certain cases, for example, when the network function is most effective when located as close as possible to the end-user. Such is the case for firewalls, diagnostic tools, IP-PBXs, traffic accelerators, NATs, and rate-limiters. An omniscient D-NFV orchestrator handles all VNFs and virtual machine (VM) infrastructure, wherever they may be located, and exploits SDN-like mechanisms to achieve optimal VNF placement.
