Flowgrammable.org is a coalition of researchers and industry engineers dedicated to improving adoption of software-defined networks and networking. Flow-level SDN, enabled by widely reusable and reused COTS network processors, is enabling an unprecedented level of software innovation opportunity. Early pioneers have often marked SDN as the dawn of a new level of "simplified networking", but such claims are struggling to be fully realized as important abstractions remain undefined. Flowgrammable seeks to fill the gap with an end-to-end vision of flow-level SDN and targeted tools to accelerate application development, network deployment, and system testing.
