[e2e] Congestion control as a hot topic in IETF

[Scharf, Michael (Michael)]

There has been some interesting research on whether a transport protocol could work without any congestion control. One reference is: B. Raghavan and A. Snoeren, "Decongestion Control", ACM SIGCOMM Workshop on Hot Topics in Networks, 2006.

Some time ago, I wondered myself whether an Internet without congestion control could work, or not. My (somehow short) insight can be found on page 67 of: http://www.ikr.uni-stuttgart.de/Content/Publications/Archive/Sf_Diss_40112.pdf

<commercial>Section 4.1 and Section 4.2 of that document have been written to give a decent introduction into congestion control, complementing Michael Welzl's excellent book on the same topic</commercial>

Yup :-).  I was astounded at the "why is congestion control important"
question.  I'm holding back, not being an expert.  I hope he gets 30+
answers ... but so far it seems to have shut everyone up.

When I was for-profit I was told "nobody ever made money on the
control plane".  That could be the problem.
