Wow! This is the first time I am learning of this technique. Hmm!

This is one reason why the internet as it currently stands should be considered just a prototype!

Will drop that in.

I have read about approach to achieve “better videoconferencing and faster trading platforms” already… Video Conferencing often uses UDP not TPC, and serious trading platforms, like High Frequency Trading, use different methods to resolve latency, they build the trading platform IN the exchange. Hopefully this just helps even more.

You still have non-deterministic failure modes, problems as you saturate the network, a mis-allocation of resources among the flows, and non-stationarity (variability of loss and delay). The underlying issues with TCP/IP aren’t being addressed: work conserving queues & excessing data in transit, trying to manipulate a system of two degrees of freedom (load/loss/delay) using just one (load/loss), non-compositionality of the performance of the queues, lack of adequate mechanisms to trade between the flows. To solve the problem, you need to change the origin of your world view. See http://www.slideshare.net/mgeddes/martin-geddes-lean-networking for more information. The future is polyservice networks that recognise that demand is heterogeneous, and creates a supply that matches it.
