Hi Xuesong,

> I agree that "minimal flooding time " is a good choice, which may differ from the traditional cc in layer 4, which is difficult to get the completion time for each flow.
> I am still a little confused about " fast brand X needs to not overrun slow brand Y while performing well with fast brand Z". Is this talking about interoperation between different company device, which may use different type of cc mechanism?


Yes, I’m talking about interoperability. 

Normally, in this working group, interoperability implies that each implementation is sending and receiving correctly formatted packets and computing correctly. This particular item adds in one other degree of complexity: timeliness. An implementation must be able to go fast or slow, depending on the needs of the receiver.
