2. Disclaimer
This is not an official IEEE 1904 WG output; just an informal update what is happening regarding Radio over Ethernet in IEEE P

3. What is IEEE TF and RoE?
IEEE specifies transport protocol and an encapsulation format i.e., RoE for transporting time-sensitive wireless radio related application streams between two endpoints over Ethernet-based transport networks.
IEEE also specifies mappers from current CPRI to native RoE.

4. Updates since Waikoloa..
Two meetings held (one virtual and one f2f).
Bi-weekly calls still running.
The first draft spec was estimated to be out by October. Goal achieved, but the draft is still in _very_ draft state i.e., D0.x versions circulated.

5. Current status Major simplifications to RoE header done:
Larger flow and packet type spaces.
No combined timestamps and sequence numbers on a single flow -> use either one.
Separate data and control packet families.
Mappers getting into shape (how to map existing ”well behaving” CPRI to native RoE and vice-versa):
”description language” for describing the payload.
”description language” for describing the control word processing and selective transport of control words.
Two modes: ”nearly” structure agnostic and structure aware.
Few more rounds ahead before D1.0..
