The Federal Aviation Administration (FAA) Telecommunications Infrastructure (FTI) network is an essential component for the day-to-day FAA mission. In this digital era where quick access to information is essential, the FTI network has grown significantly and is used to transport data, services, and information for the National Airspace System (NAS). Whether the follow-on network FTI-2 is completely on‐premises, cloud‐based, or a hybrid, it provides the foundation communication links that the FAA needs in order to run their applications and deliver services.
This paper examines Software Defined Networking (SDN) and Network Function Virtualization (NFV) technology as components of automating network and cloud service provisioning for enabling increased levels of accuracy in rapid services turn-up and restoration with a flexible, adaptable and scalable network infrastructure. While we are discussing both technologies in this one paper they are separate technologies that can complement each other but are not required to be deployed together. An example would be to deploy SDN to the current FAA fiber infrastructure to allow more efficient use of fiber for redundancy, without deploying NFV in the network. Conversely NFV can be deployed as network or customer premise devices without SDN control.
To illustrate the progress of the adoption of SDN/NFV technology, two Service Providers have provided input on the current status and potential future states for SDN/NFV technology in their networks. Both Service Providers examples show some of the benefits of deploying an integration of both technologies. The group expresses our gratitude for these two submissions.
