Xiaobing,

Let me see if I understand you correctly.

Let us assume that we have a 100GE PHY with on 100GE FlexE Group
and that FlexE Group have 5 FlexE Clients.

If an Ethernet frame is to be transmitted over the FlexE Group, are you
saying that it is arbitrary which FlexE Client it will be transmitted
over??

/Loa
