Multipath TCP (MPTCP) is an ongoing effort of the Internet Engineering Task Force's (IETF) Multipath TCP working group, that aims at allowing a Transmission Control Protocol (TCP) connection to use multiple paths to maximize throughput and increase redundancy.[1]

In January 2013, the IETF published the Multipath specification as an Experimental standard in RFC 6824. It was replaced in March 2020 by the Multipath TCP v1 specification in RFC 8684.
