Multipath TCP is a TCP extension that allows a TCP connection to send/receive packets over different interfaces. Multipath TCP has various use cases, including : enable smartphones to use their WiFi and 3G interfaces simultaneously or in failover modes improve TCP performance in datacenters to exploiting multiple paths improve performance on dual stack hosts running IPv4 and IPv6 ...Designing such a major TCP extension has been a difficult problem and took a lot of effort within several research projects. The work started within the FP7 Trilogy project funded by the European Commission. It continues within the CHANGE and Trilogy 2 projects.After five years of effort, we are getting close to a wide adoption of Multipath TCP. In January 2013, the IETF published the Multipath specification as an Experimental standard in RFC 6824 In July 2013, the MPTCP working group reported three independent implementations of Multipath TCP, including our implementation in the Linux kernel. To my knowledge, this is the first time that a large TCP extension is implemented so quickly. On September 18th, 2013, Apple releases iOS7 which includes the first large scale commercial deployment of Multipath TCP. Given the marketing buzz around new iOS7 releases, when can expect tens of millions of users who will use a Multipath TCP enabled device.
