[ih] pretty good video on internet history

[Craig Partridge]

Complete side comment.  Every time people mention SATNET I'm reminded of
when I used SATNET as a delay line to debug TCP and RDP implementations on
weekends c. 1985.  I had developed a testing tool that tracked connection
states and displayed them in real-time (on a SUN workstation) and the
round-trip delay to GOONHILLY-ECHO (an IP echo server) was perfect -- I
could literally watch the effect of each packet as it arrived.  (That was
how I figured out issues in TCP round-trip estimation and also the benefits
of extended acknowledgements).

Then I made the mistake of mentioning I was doing this to a senior UCL
person, who chewed me out for using, in his words, "one of the most heavily
used links in the Internet" for testing purposes. :-)
