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.
2Slide3
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.
3Slide4
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.
4Slide5
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..
