[ih] History from 1960s to 2025 (ARPANET to TCP)

[Barbara Denny]

I also think the packet speech effort contributed to how TCP evolved from the original IEEE paper.  This program probably started in 1973 by ARPA and was called  Network Secure Communications Program . Packet speech doesn't require reliability (no packet loss).

And satellite.  And enterprise vs. backbone.

As soon as this comms tech has to deal with extensive diversity AND with 
very high reliability (and performance) it needs to be a /independent/ 
infrastructure mechanism.

Within-host is fine, for servicing leaf nodes.  But not for 
infrastructure service.
