AFAIK multi-path is not too common, though most people who do multipath are using MPTCP.
Last I checked, It's part of LTE standard, but used exclusively in South Korea. Some providers across the world provide multi-path gateways: in France, OVH has OverTheBox which is line-provider agnostic, Free has ADSL+4G aggregation where fiber isn't available. In Switzerland, Swisscom also has some multi-path offer.
Also, Apple's Siri uses MPTCP. (And developers love the fact that only Siri can use it, and not other apps).
Google/Android said no to MPTCP, saying QUIC/HTTP3 already has the provisions needed to do multipath, but I don't know if Google actually uses it somewhere.
- mwint 5y ago> and not other apps Looks like there’s been an API for at least a few years. http://blog.multipath-tcp.org/blog/html/2017/07/05/mptcp_experiments_on_ios_11_beta.html http://blog.multipath-tcp.org/blog/html/2017/07/05/mptcp_exp...
- lapinot 5y agoFrom experience, Free's ADSL+4G aggregation is stupid. The router needs ADSL to be up all the time and aggregation is unpredictable and opaque. Being the carrier for both ADSL and 4G would've enabled them to do multi-path magic and assign the same IP to both endpoints yet they don't. It seems to be basic bonding.
- m0dest 5y agoQUIC has some basic features for migrating a session to another link, but it doesn't support multipath in that sense. Multipath QUIC (MPQUIC) is a hot research area right now, and it's being standardized. MPTCP's design was fundamentally incompatible with QUIC's UDP transport and session model. From what I understand, neither MPTCP nor MPQUIC are designed to share multipath routing via a gateway (e.g. a bunch of devices sharing a multipath aggregation of 3 4G modems). It's all designed for a single device with multiple interfaces.
