Hi Robert, Dealing with a pizza box is straightforward. In section 3.3.2 we describe the interface PSP TLV. This carries the power savings potential for an interface. The power consumption of the QSFP would belong in that TLV.
The low link utilization for transition to power sleep is a configurable level. The use of power groups would not change the flex algo topology. Traffic would remain within the same algorithm.
