Bug 730608 – MultiPath TCP - Linux Kernel implementation

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Joakim Tjernlund 2020-07-03 12:24:38 UTC]

http://multipath-tcp.org

MultiPath TCP (MPTCP) is an effort towards enabling the simultaneous use of several IP-addresses/interfaces by a modification of TCP that presents a regular TCP interface to applications, while in fact spreading data across several subflows. Benefits of this include better resource utilization, better throughput and smoother reaction to failures. Slides - explaining MultiPath TCP - are available in .pdf and .pptx format. You can also have a look at our Google Techtalk about MPTCP, or the MultiPath TCP tutorial given by Olivier Bonaventure at the IETF87.

What is it you would like to get packaged? A kernel module? A kernel fully implementing MPTCP (e.g. Linux >5.8)? Userland tools?

[Comment 2 Jeroen Roovers (RETIRED) 2020-07-03 12:37:16 UTC]

For userland, related sys-apps/iproute2 changes are at [0].

sys-apps/iproute2 is not at 5.8 yet. :-)

Oh, but I can wait :)

[Comment 9 Jeroen Roovers (RETIRED) 2020-07-03 13:34:11 UTC]

You can install a kernel 5.8 snapshot and =sys-apps/iproute2-9999 right now!
