Hi Dave 

and thanks for the heads up. 
Interesting read even though I am not working with datacenters 

Read the paper and see that the authors stop short of the DCQCN marking
style where packets are marked with a probability based on queue length. It
would have been interesting to see that also compared to ECN#.
