Simultaneous open

Latest comment: 1 day ago1 comment1 person in discussion

Should we discuss TCP simultaneous open in this article? While it isn't very common, it is a standardised way of opening a TCP connection and useful in, for example, holepunching. There is also lot of misinformation on it on the internet. While the state diagram mentions it, there is no description on the actual page. JasTheHash (talk) 11:17, 16 October 2026 (UTC)Reply
