  5. 5. 5 Copyright © 2014 Juniper Networks, Inc. Presented at Juniper New Network Day in Moscow , 1st April 2014 HOW THE OPERATORS SEE IT – EXTRACT FROM THE PAPER - QUOTE:- “Network Functions Virtualisation aims to address these problems by leveraging standard IT virtualisation technology to consolidate many network equipment types onto industry standard high volume servers, switches and storage, which could be located in Datacentres, Network Nodes and in the end user premises. We believe Network Functions Virtualisation is applicable to any data plane packet processing and control plane function in fixed and mobile network infrastructures. We would like to emphasise that we see Network Functions Virtualisation as highly complementary to Software Defined Networking (SDN). These topics are mutually beneficial but are not dependent on each other. Network Functions can be virtualised and deployed without an SDN required and vice-versa.”
