Abstract:
Software Defined Networking proposes the separation of the control
plane from the data plane in the network nodes and its logical
centralization on a control entity. Most of the network intelligence
is moved to this functional entity. Typically, such entity is seen
as a compendium of interacting control functions in a vertical, tight
integrated fashion. The relocation of the control functions from a
number of distributed network nodes to a logical central entity
conceptually places together a number of control capabilities with
different purposes. As a consequence, the existing solutions do not
provide a clear separation between transport control and services
that relies upon transport capabilities.
This document describes a proposal named Cooperating Layered
Architecture for SDN. The idea behind that is to differentiate the
control functions associated to transport from those related to
services, in such a way that they can be provided and maintained
independently, and can follow their own evolution path.
