What Ever Happened to SCTP?

In the mid-2000s this technology seemed to be up and coming. The world has become ever more mobile. The need for this technology has only increased.

So what happened?

The networks, OSes, ... weren't ready to accept a new protocol at such a low level, so it never worked reliably over random public connections and stayed in a niche for internal use cases. Things like QUIC, WebRTC, MP-TCP, ... rebuild aspects of it over TCP or UDP to get around this problem.

I guess that makes sense. I remember doing a research project in school and it seemed then like it would be the future. IoT and mobile phones would definitely benefit from a connectionless protocol like that.

That is the very reason I use `mosh` to connect to my servers. My laptop isn't always on the same internet connection and I'd prefer not to have to reconnect all the time.

Turns out, there is a lot of advanced routers, firewalls, IDSes, etc.. which like to inspect and filter the traffic, and they often drop unknown protocols.

As a result, new IP-based protocols are likely to have the connectivity problems. So all the development moved to be UDP based.
