   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.
