Software Driven Networks (SDN) is an approach to networks that
enables applications to converse with and manipulate the control
software of network devices and resources. SDNs are comprised of
applications, control software, and interfaces to services that
are hosted in an overlay or logical/virtual network as well as
those possibly same components that comprise the underlying
physical network. Modern applications require the ability
to easily interact and manipulate these resources. Applications can
benefit from knowing the available resources and from requesting
that the network makes the resources available in specific ways.
To this end, there is a requirement to couple applications more
closely to the underlying resources on which they depend, consume
and interact with.
SDN infrastructure and components exist in most deployed networks
today. Some of these components are being standardized by various
organizations, as as well some being already standardized by the
IETF. However, no standards or open specifications currently exist
to facilitate end-to-end operation of a software defined network,
specificlly one that provides open APIs for applications to control
the network services and functions offered by device control planes
or other "controlling" software. The goal of this document is to
outline the problem area of SDN for the IETF.
