Interesting line of discussion passed through my email regarding the future of TCP. In particular, Alex Cannara decided to take on a few of the more “conservative” elements on dealing with end-end flows by interior management of links.
As Alex puts it: “Apparently, a great bias has existed against this sort of design, which is actually very successful in other contexts”. Even a very “big old name in Internet Land” liked this type of approach, for the “…reason it [TCP] requires the opposite of backoff is because it doesn’t have the visibility to determine which algorithm to choose differently as it navigates the network at any point in time. But if you can do it hop by hop you can make these rules work in all places and vary the algorithm knowing your working on a deterministic small segment instead of the big wide Internet.”
Let’s take this further.
