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.  ITU-T SG15 has endorsed the OIF FlexE
   data plane as 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
   requirements.  What kind of models should we use when configuring
   FlexE capable equipment, how to configure the FlexE group and FlexE
   client, and what kind of parameters do we need to take into
   consideration when configuring FlexE group and FlexE client.  The
   analysis is based on the description in section 7 and 8 of [ITU-T
   G.8023] and FlexE IA 2.0.
