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.
- jerkstate 9y agoIf you have multiple ISPs in your datacenters, you can announce different IP blocks over each upstream at each site and configure full mesh MPTCP between your sites to expose as much path diversity as possible, and have MPTCP switch to the most reliable path(s), kind of like a poor man's MPLS (in my experience bulk internet bandwidth is significantly cheaper than MPLS). I've implemented this as a demo not carrying a ton of traffic and it seems to work really well, but never got around to doing it full scale. Would love to do so.
- toast0 9y agoI 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?
- londons_explore 9y agoGoogle doesn't support MPTCP. They think QUIC streams (supported by Chrome and google services) serve the same purpose better.
- baybal2 9y agoBest used for cross-DC traffic over public networks if you have access to multiple physical links, and no transparent DC-Internet routing
- jlgaddis 9y agoWithin a datacenter, you'd be more likely to use LACP and/or ECMP.
- horstFeistel 9y agoECMP works great with MPTCP :-)
- dogecoinbase 9y agoThough, with many LACP hash implementations, you end up de facto restricted to a single link per TCP flow.
