T/TCP (Transactional Transmission Control Protocol) is a variant of the Transmission Control Protocol (TCP). It is an experimental TCP extension for efficient transaction-oriented (request/response) service. It was developed to fill the gap between TCP and UDP, by Bob Braden in 1994. Its definition can be found in RFC 1644 (that obsoletes RFC 1379).

Details [edit]
This protocol is faster than TCP and delivery reliability is comparable to that of TCP. Unfortunately, T/TCP suffers from several major security problems as described by Charles Hannum in September 1996.[1][2] It has not gained widespread popularity.
RFC 1379 and RFC 1644 that define T/TCP were moved to Historic Status in May 2011 by RFC 6247 for security reasons.
Alternatives [edit]
TCP Fast Open is a more recent alternative.
