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.
