Abstract:
Software-Defined Networking (SDN) can in general be defined as a new
approach for network programmability. Network programmability refers
to the capacity to initialize, control, change, and manage network
behavior dynamically via open interfaces as opposed to relying on
closed-box solutions and propietary-defined interfaces. SDN
emphasizes the role of software in running networks through the
introduction of an abstraction for the data forwarding plane and, by
doing so, separates it from the control plane. This separation
allows faster innovation cycles at both planes as experience has
already shown. However, there is increasing confusion as to what
exactly SDN is, what is the layer structure in an SDN architecture
and how do layers interface with each other. This document aims to
answer these questions and provide a concise reference document for
SDNRG, in particular, and the SDN community, in general, based on
relevant peer-reviewed literature and documents in the RFC series.
