It's a matter of degree, right?


>> However, I do believe you should know how the Internet works.  And if you honestly believe packets in a single stream cannot travel over different paths, you clearly do not.  And before you come back with BS about "normal operation" or such, realize your statement was far more "factually incorrect" than what the video said about private interconnects.

Yes, flow switching is common, but it is by no means guaranteed.  Lots of people do per-packet across LAG bundles.  The Internet topology 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?


> But I'll shut up after this, I'm obviously not jaded enough like you other people to just swallow this as "advertisement". I expected a correct factual way of describing how the Internet works including IXPs, not an IXP advertisement. My expectations were obviously wrong from the 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.
