It is pity that, I didn’t bother to learn or understand this topic from EPFL. Many a times I had casually walked across and through the rooms where a good flair of this work got done, but never made it to the details. Now, on a completely different context, I came across the paper by Ozger, Leveque and Tse on the capacity scaling. It is fascinating indeed. A gist of this was there for me to grab during one of the IPG seminars, but then it was all misty and cloudy. Over this weekend, I am going to read the paper in a little more detail.
