I found two papers which state that with ideal fountain
code,there is generally no congestion collapse.Efficiency
remains higher than 90% for most network topologiesas long as
maximum source rates are less than link capacity by one or two
orders of magnitude. Moreover, a simple fair drop policy
enforcing fair sharing at flow level is sufficient to
guarantee 100% efficiency in all cases. I refer to several
papers on the congestion problem when fountain code is used.

Don't we compare peaches and oranges here?<br>

When we talk about TCP, we talk about a reliable protocol. Are
digital fountain codes reliable??<br>
