Each I. The translation work of the I. His mother, Velva Diede Walden, taught elementary school; his father, Clarence, taught high school chemistry and physics. Walden was 4.

But so consuming was his passion for the game that he left college after one semester because of poor grades, his wife said. Read the papers cited in the first and third items below and read the first group of RFCs under item 4 below to for lists of these people and the issues they were thinking about. What I was mostly grappling with was if the protocol were symmetric it could "loop" -- if commands passed each other over the net, then the responses passed each other, and those kicked off other responses, etc.

One [loop] that came to mind that I recall thinking about back then was with one end saying "I'll send echoes" and the other saying "I'll echo locally". They cross, and each then responds "OK you echo". Each now has gotten a change of state [since each said they weren't going to echo and now has been told to] and so each sends another "OK I'll send echoes" and "I'll echo locally" and around they go Another important idea that it handled was that it was extensible: it provided for the notion that one side could ask about something unknown and that'd be OK [and the negotiation would do the right thing], so there could be fancy-hosts and not-so-fancy ones and they could negotiate to make as clever a connection as they could while still gracefully handling hosts that could only deal with not-so-clever ones.
