After quite some time, I once again thought about your paper.

Even the name "decongestion" is misguiding. As DPR stated: Erasure codes 
do not obviate the need of congestion control.
And the "decongestion" in your paper does not "decongest" the net - i.e. 
deliver the network from load which cannot be handled.
Actually, it is some kind of degradation, because in case of TCP, the 
goodputs are throttled.

Congestion is not a goodput issue but actually a throughput issue.
