draft-contraras-layered-sdn is proposed for publication as an Informational RFC
on the Independent Submissions Stream.
This document describes an approach named Cooperating Layered Architecture for
Software Defined Networking. The idea is to differentiate the control
functions associated with transport of packets from those functions related to
services. This separation is done in such a way that the functions can be
provided and maintained independently, and can follow their own evolution paths.
This document was first brought to the SDNRG where it received some discussion
and was presented to the Research Group at a face-to-face meeting. The SDNRG
was closed, and the authors have been looking for a place to archive this work:
the chairs of the former RG suggested an Independent Submission. The authors
are clear that the document is their own work and, while it has received input
from the IRTF, it is not the product of the IRTF or the IETF.
The ISE pinged the IRTF chair to see whether there were nay concerns with
publication, and received no response.
This version of the document has benefitted from commissioned reviews by Gert
Grammel and Georgios Karagiannis, and also from reviews by the previous and
current ISEs. The document has been updated accordingly.
