Thank you both (Marcin and Greg) for the links, they have made for
some great reading tonight. It would appear that I have introduced a
slight tangent from the goal of this topic. The main discussion here
was regarding an overhaul of TCP, whereas my Briscoe suggestion is
more of an architectural overhaul which leads to many other changes
(infrastructural, economical and protocol) in the network.
Briscoe's somewhat undiplomatic introduction of his idea seems to have
elicited an initially negative response, however I happy to see that
others have seen his ideas to have merit and hence test his reasoning.
I surmise that the big question now is, do we go with a small step
(enhanced congestion detection) or a jump (total reworking of network
I am glad to say that whatever is decided, it will most likely be
implemented far faster than IPv6. As we will not have a specific
feature to buy us time from congestion, unlike what NAT did for IPv4.
