It's a matter of degree, right?

interconnects.

looking at the movie. Any core router ECMP algorithm that sprays L4 =
sessions like that will cause re-ordering which is bad, mkay.

Yes, flow switching is common, but it is by no means guaranteed.  Lots =

changes do not wait until all TCP sessions are complete.  Not everyone =
does flow switching.  Etc.

Which all means, as I said in my last sentence above, that you are doing =
exactly what you accuse them of doing - only worse.  Your "facts" are =
not facts, the most you can accuse this video of is not explaining =
things fully.

I guess the only question left is: What are you advertising?

response I'm seeing.

I wouldn't call you "jaded" when you do what you accuse others of doing.

And to be clear, you got "a correct factual way of describing how the =
Internet works including IXPs".  It may not have been complete, but if =
you honestly expected a complete description of the Internet in a film =
of /any/ length ... well, words fail me.
