Improving the deployability of Multipath TCP, part 2
Improve MPTCP support in the Linux kernel
Multipath TCP (MPTCP) is a standardised technology extending TCP and invented in Europe. TCP is one of the key protocols of the TCP/IP protocol stack, designed in the 1970s when hosts were attached to the network through a single cable. Today's hosts have several network interfaces, but TCP only uses one of them for a given connection. Multipath TCP solves this problem by enabling TCP connections to exchange packets over different network interfaces. With the current version of MPTCP in the Linux kernel, most of the features listed in the RFC8684 are implemented. Basic use-cases are supported but still it doesn't mean the solution is covering all needs and is easy enough to use. In short, MPTCP works well in controlled environments but there is room for improvement in heterogeneous ones. Some work is then still needed to cover more use-cases plus to improve the usability and performances in order to have Multipath TCP adopted by a broader audience.
