On April 7, 1969 the first Request For Comments (RFC) standard that defined the messaging protocol that would later become the series of tokens and procedures that became the modern internet. RFC 1 was the core of the new internetworked world:
During the summer of 1968, representatives from the initial four sites met several times to discuss the HOST software and initial experiments on the network. There emerged from these meetings a working group of three, Steve Carr from Utah, Jeff Rulifson from SRI, and Steve Crocker of UCLA, who met during the fall and winter. The most recent meeting was in the last week of March in Utah. Also present was Bill Duvall of SRI who has recently started working with Jeff Rulifson.
Somewhat independently, Gerard DeLoche of UCLA has been working on the HOST-IMP interface.
I present here some of the tentative agreements reached and some of the open questions encountered. Very little of what is here is firm and reactions are expected.
This got the ball rolling and through the next decade, computer hobbyists and information scientists finalized the basic internet which forms the foundation of what we use today.
