Re: [44net] AXUDP spec

Well if one first dropped the 'AX' portion of your question and re-read it more as "What is UDP ?" one might get this. A short answer is "UDP (User Datagram Protocol) is an alternative communications protocol to Transmission Control Protocol (TCP) used primarily for establishing low-latency and loss tolerating connections between applications on the Internet. ... Both protocols send short packets of data, called datagrams. " Then a novice to both amateur radio and packet might ask about the 'AX' portion. While I can't be certain, I believe the AX prefix to UDP might have been added to simply specify "in amateur radio uses" most likely borrowed from the 'AX.25' protocol name. And while you've been in ham and packet radio for a good many years, Michael, I'll add a definition of the AX.25 protocol here for those that are new(ish). "AX.25 (Amateur X.25) is a data link layer protocol derived from the X.25 protocol suite and designed for use by amateur radio operators. It is used extensively on amateur packet radio networks. AX.25 v2.0 and later occupies the data link layer, the second layer of the OSI model. " I'm not entirely sure if that answers your question, but I hope so.
