IEEE P1904.3 TF Radio over Ethernet update Jouni Korhonen IEEE 802.1TSN @Dallas 2015

Disclaimer This is not an official IEEE 1904 WG output; just an informal update what is happening regarding Radio over Ethernet in IEEE P1904.3.

What is IEEE 1904.3 TF and RoE? IEEE 1904.3 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 1904.3 also specifies mappers from current CPRI to native RoE.

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.

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..
