Long ago and far away I used to work for a company called Charles River
Data Systems. During 1987-19889 Charles River UNOS realtime UNIX was ported
to the then new Intel 80386. One offshoot was a project to build backend
databases accelerators for Vax/VMS systems running Oracle. The "accelerator"
backed was connected to the Vax via a private 2 node ethernet network. 

The two main developers on the project came up with a non-TCP networking
protocol that looked a lot like RFC 998. It gave them a 30% or so increase
in throughput over TCP/IP and CRDS UniverseNet. In the end they went with
TCP/IP, because TCP/IP was an important checkoff box on government contracts.
(As opposed to the evil DECNET) :-)

Mind you, that was a long time ago, and it is doubtful that any of that code
lives. When they wrote that code there were about 500 systems hooked to the
internet, with a lot of other systems using UUCP. The code never got used on
a shared network.

Meanwhile, today the internet is like trying to suck a small, thin stream of
pure water through a large pipe filled with sewage.
