The other SFTP that never was
For reasons, I'm doing some research into the history of FTP (File Transport
Protocol) when I come across an RFC (Request For Comments) for SFTP. Only
this isn't the SFTP (Secure File Transport Protocol) [1] that is used today,
but instead the Simple File Transfer Protocol [2] from 1984. Unlike TFTP
(Trivial File Transport Protocol), it uses TCP (Transmission Control
Protocol), and unlike FTP, it only uses a single network connection.
But this bit is why I'm writing about this:

That “other protocol” would take several more years to be invented, and then
take over the networking world.
