I think this was Computer Networks by Andrew S. Tanenbaum.

Pages are sequenced packets. Rip up the book, blow it in the breeze across
the fence. Neighbor looks for pages upto some timeout, and then requests
retransmission of missing pages -- is that what you recall?

Sender has to have additional copies of the book to rip up for rexmit... that
was left as an exercise for the reader :-)

PS: Prof Tanenbaum is also credit with other gems such as "do not
underestimate the bandwidth of a horse carriage rattling down the carriage
way", and "The best thing about standards is that there are so many to
choose from"

... that used an analogy of 2 neighbors communicating over a fence to
explain how TCP works.  I'd love to get my hands on a copy of that book.
Does anyone else remember that book or the analogy?
