Software-Defined Networking (SDN) advocates for the separation of the
control plane from the data plane in the network nodes and its
logical centralization on one or a set of control entities. Most of
the network and/or service intelligence is moved to these control
entities. Typically, such an entity is seen as a compendium of
interacting control functions in a vertical, tightly 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 rely
upon transport capabilities.
This document describes an approach called Cooperating Layered
Architecture for Software-Defined Networking (CLAS), wherein the
control functions associated with transport are differentiated from
those related to services in such a way that they can be provided and
maintained independently and can follow their own evolution path.
