RE: [RPRWG] More comments on preemption







Could you clarify your statement "... definitely takes us away from Ethernet"?

If you are targeting your comment at the Ethernet PHY layer:  the Ethernet (100
& 1000) uses 8B/10B encoding.
There are some "spare symbols" not used (if I am not mistaken) that could be
redefined to mean "IDLE/Escape".

This is very good idea to manage pre-emption and other QOS related
considerations but this definitely takes us away from  Ethernet.
