Could someone add a section explaining how UDP is actually useful (which it obviously must be), or at least explain to me? I don't see how you could use it as you cannot guarentee packages will be received.
"The internet telephony app will try and do without lost voice data rather than waiting for a resend." "try and do"? If you "do", "try" is understood and redundant. Change "try and do" to one of these two: "try to" or "and do". If "try" is needed for the sentence, we would have to put "try" in front of most verbs. We would start sounding like the pidgin english of Hawaii, as in "try stay go". (Yes I put the period outside the quotation marks deliberately. No matter the rule, the period is not part of the quoted material.) —Preceding unsigned comment added by 207.5.245.62 ( talk) 13:34, 29 March 2008 (UTC)
UTP is not garunteed when sending a message, but thats where TCP comes in. TCP resends the part of the message that doesn't get received. If no part of the message is received then TCP resends the entire message again
But I corrected several things like *space**period* and "dotdot" at the end of sentences. —Preceding unsigned comment added by 216.212.238.139 ( talk) 00:51, 3 July 2008 (UTC) TTTT
Should the discussion here about the comparison between TCP and UDP use the term segments instead of packets?

It is clear from the RFC that User Datagram Protocol is what UDP refers to. The article mentions alternative mappings: Universal Datagram Protocol and Unreliable Datagram Protocol. Are these incorrect alternative names worth noting (and perpetuating)? -- Kvng ( talk) 14:29, 14 July 2010 (UTC)
Not sure what to do about this, but wikipedians might have some suggestions. UDP (like TCP) was in active development prior to the RFC that documented it was issued. So the 1980 date for its creation may confuse people who know the history of the Internet protocol development. In particular, the decision to split the original TCP design into three protocols was taken in 1977, three years before RFC768 froze its design. What was a purely virtual circuit model prior to that point was split into the IP layer (now IPv4) which carried host-to-host datagrams between gateways (now called routers) and two higher level protocols, UDP and TCP. This was the result of strong advocacy for support of a class of uses that could not accept the constraints imposed by reliable, exactly once, in-order delivery.
Not sure the best citation for this, but many Internet histories discuss this event. The packet formats and behavior of the three different protocols were implemented and in use soon after that at a number of sites, well before 1980. AdScientiam ( talk) 19:21, 4 December 2017 (UTC)
It says in the first paragraph of the lead "Prior communications are not required in order to set up communication channels or data paths." However would it not be necessary to use something like ARP to obtain a MAC address for the IP address used by UDP? Graham.Fountain | Talk 12:22, 5 August 2021 (UTC)
