RE: [EFM] Re: OAM - this is Ethernet Bob but not as we know it


So is deterministic delivery of OAM data over the OAM transport an objective
for the OAM transport track or not? That bit is still unclear to me despite
your clarification. If it is not an objective I guess I have the option to
put it up as a motion at the March meeting.

This is not an objection, it's a request for clarification. (Stupid arrows
T-shirts may be pointed at me at will, I have a thick skin, and I am renown
for my persistence.)

For the wags I don't think we are in the realms of quantum physics yet.
Ethernet frames are bigger than photons even at 10G. We may have to start
worrying about wave particle duality at a tera bit :0)

Thanks Matt.  That's definitive and we need that in the EFM work.  Anybody
