This document presents a framework for Software Defined Networks
(SDN). The purpose of the framework is to provide
an overall picture of the problem space of SDN and to describe the
relationships among the various components necessary to manipulate
the components that comprise SDNs. SDN requires the specification
of several key components including an "orchestrator" and various
"plug-ins" between the orchestrator function and network resources.
In addition to this, an orchestrator will require interconnection
with standard policy bases, as well as other orchestrators in
distributed environments or insofar as to support high-availability
and fault-tolerance capabilities. To this end, several interfaces
and mechanisms to address issues such as enabling the orchestrator
to manipulate and interact with the control planes of devices such
as routers and switches, as well as a discourse between different
orchestrators will be described. The intent of this document is
to outline what each interface needs to accomplish, and to describe
how these interfaces and mechanisms fit together, while leaving
their detailed specification to other documents.
