If you're on a cable modem right now, did you know your downstream internet connection is happening over a video stream?
Yup. Downstream internet on DOCSIS is an MPEG2 transport stream, just like the TV you watch. Which does frame reordering, retransmission, etc etc. TCP in an MPEG2 stream. which itself smells an awful lot like TCP over RF
There was this moment when I went to work for Network Engineering at Time Warner Cable where they handed me the specs and giggled. A few minutes later, there's the sound of sungo yelling "ARE YOU KIDDING ME WITH THIS SHIT? THIS IS A PRANK RIGHT?" It was not a prank.
