Lopez, M. Boucadair, P. Iovanna Status: Informational Stream: Independent Date: May 2019 Mailbox: luismiguel.contrerasmurillo@telefonica.com, cjbc@it.uc3m.es, diego.r.lopez@telefonica.com, mohamed.boucadair@orange.com, paola.iovanna@ericsson.com Pages: 21 Characters: 45229 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-contreras-layered-sdn-03.txt URL: https://www.rfc-editor.org/info/rfc8597 DOI: 10.17487/RFC8597 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.
