MPTCP's bandwdith aggregation properties are cool---you can effectively use all your network interfaces for (MP)TCP connections. Has anyone deployed it in data-center/cloud environments? I know that both Apple and Android support it for the mobile devices to use WiFi and LTE at the same time.

Within a datacenter, you'd be more likely to use LACP and/or ECMP.

ECMP works great with MPTCP :-)

TL;DR: can you connect to this website with an IETF experimental standard that hasnt been upstreamed into the linux kernel and only started using function pointers in 2015? No. http://people.netfilter.org/pablo/netdev0.1/papers/Shaping-t...

Be that as it may, it's available to apps in ios 11, so it seems likely to get more traction.

interestingly enough this is largely due to the ios subsystems use of MPTCP for siri. It also shows up in F5 products, albeit one must wonder if its ever advertised for use in genuine load balancing

So what's the current status of the upstreaming work? It sounds like there's a good start discussed in the paper, in removing a lot of conditional and duplicated code and using some more cleanly separated layers, but that was two years ago, what's happened since?

Though, with many LACP hash implementations, you end up de facto restricted to a single link per TCP flow.

I know there are Android builds you can install with mptcp support, but I didn't think it had made it into mainstream android phones, do you have a link?

Google doesn't support MPTCP.

They think QUIC streams (supported by Chrome and google services) serve the same purpose better.
