Xiaobing,

The way I read you is that if I send an Ethernet frame over a FlexE
interface all the bits/bytes of this frame will be transmitted on the
same FlexE Client, right?

What I tried to ask repeatedly is that if I have e.g. three Ethernet
frames, and can identify frame 1 and 3 as belonging to the same flow,
while frame does not belong to that same flow, can I make sure that:

Frame 1 is transmitted over FlexE CLient-1
Frame 2 is not transmitted over FlexE Client-1
Frame 3 is transmitted over FlexE CLient-1

Is that possible????
