Mallik Tatipamula is the Vice President of Service Provider and Cloud Solutions at F5 Networks. He has over 23 years of experience in telecommunications and networking technologies. The presentation outlines F5's perspective on deploying Network Functions Virtualization (NFV) in phases, beginning with simplifying the SGi network and virtualizing value-added services platforms, then virtualizing control plane functions and finally access and core network elements. The goals are to make networks more programmable, simplify operations, and lower costs through a flexible, software-based architecture.
