Abstract:
Software-Defined Networking (SDN) refers to a new approach for
network programmability, that is, the capacity to initialize,
control, change, and manage network behavior dynamically via open
interfaces as opposed to relying on closed-box solutions and their
associated proprietary 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, a product of the IRTF Software-
Defined Networking Research Group (SDNRG), addresses these questions
and provides a concise reference for the SDN research community based
on relevant peer-reviewed literature, the RFC series, and relevant
documents by other standards organizations.
