T/TCP (Transactional Transmission Control Protocol) was a variant of the
Transmission Control Protocol
The Transmission Control Protocol (TCP) is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is common ...
(TCP).
It was 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). It is faster than TCP and delivery reliability is comparable to that of TCP.
T/TCP suffers from several major security problems as described by Charles Hannum in September 1996.
It has not gained widespread popularity.
RFC 1379 and RFC 1644 that define T/TCP were moved t
Historic Statusin May 2011 by RFC 6247 for security reasons.
