Line 1:
The term ''half-open'', when referring to [[Transmission Control Protocol|TCP]] connections, has two distinct meanings.
 
According to RFC 793, a TCP connection is referred to as ''half-open'' when the host at one end of that TCP connection has crashed, or has otherwise removed the socket without notifying the other end. If the remaining end is idle, the connection may remain in the half-open state for unbounded periods of time.
 
Nowadays, however, the term ''half-open connection'' is most often used to describe [[embryonic connection]]s.
