1.  Introduction

   OIF published the first version of FlexE Implementation Agreement in
   March 2016, aiming to provide a generic mechanism for supporting a
   variety of Ethernet MAC rates that may or may not correspond to any
   existing Ethernet PHY rate.  SG15 in ITU-T has endorsed the OIF FlexE
   data plane and parts of [ITU-T G.872], [ITU-T G.709], [ITU-T G.798]
   and [ITU-T G.8023].  The Recommendations depend on or are based on
   the FlexE data plane.

   This draft is intended to trigger discussion of the FlexE control
   architecture according to the analysis in section 2.  What kind of
   architecture should we employed when configuring FlexE equipments,
   how to configure the FlexE group and FlexE client, and what kind of
   parameters do we need to take into consideration?  The analysis is
   mainly based on the description in section 7 and 8 of [ITU-T G.8023],
   which is "Characteristics of equipment functional blocks supporting
   Flex Ethernet interfaces".
