Software Defined Networking at the Tactical Edge

ABSTRACT
Software defined networking has now been accepted by the industry. However, there are several variations of it. In this talk, we discuss these variations and explain what SDN is and what it is not. After a brief discussion of recent trends, we argue that the future lies in extending SDN concepts to virtualizing cloud computing. This allows applications to span multiple clouds of varying sizes and at different locations. This multi-cloud has applications in industry, networking, and defense applications.

This talk covers the following topics:

• What SDN is Not?
• Three Features that Define SDN
• Software Defined Anything (SDx)
• Ten Benefits of SDN
• Centralized vs. Distributed
• Four Confusions About SDN

• SDN Evolution
• Flavors of SDN
• Trend: Micro-Cloud Computing
• Past: Data in the Edge (CDN)
• Trend: Computation in the Edge
• Trend: Multi-Cloud Hierarchy
• NFV Multi-Cloud Use Case
• Any Function Virtualization (FV)
• Networking App Market: Lower CapEx
• SDN Past
• SDN Future
• OpenADN Multi-Cloud Management
• Mobile Healthcare Use Case
• Tactical Application
• Multiple Applications and Providers
