  GMPLS Routing and Signaling Framework for Flexible Ethernet (FlexE)
                      draft-izh-ccamp-flexe-fwk-03

Abstract

   As different from earlier Ethernet data planes FlexE allows for
   decoupling of the Ethernet Physical layer (PHY) and Media Access
   Control layer (MAC) rates.

   Study Group 15 (SG15) of the ITU-T has endorsed the FlexE
   Implementation Agreement from Optical Internetworking Forum (OIF) and
   included it, by reference, in some of their Recomendations.

   This document specifies the use cases of FlexE technology, GMPLS
   control plane requirements, framework, and architecture.
