While I was a little late to the party (our TCP didn’t start to
get written until early 1981), I don’t recall any discussion of
GBN at the time. Perhaps that was a term of art invented later to
describe all this. The retransmission mechanism was to send
unacknowledged data from the "left window edge” of the TCP “send
window”. By definition, that’s where all of the unacknowledged
data in the sliding window existed.

<div>The decision of how much data to send was implementation
specific. I can’t imagine sending less than a whole TCP MSS
on a retransmission attempt.

As far as I had a glance at the sources yesterday late in the
evening (or today, early in the morning ;-)) this seems to be
avoided. <br>
(In the context of the "silly window syndrome".)
