[$] The Homa network protocol

The origins of the TCP and UDP network protocols can be traced back a full
50 years. Even though networks and their use have changed radically
since those protocols were designed, they can still be found behind most
networking applications. Unsurprisingly, these protocols are not optimal
for all situations, so there is ongoing interest in the development of
alternatives. One such is the Homa
transport protocol, developed by John Ousterhout (of Tcl/Tk and Raft fame, among other accomplishments),
which is aimed at data-center applications. Ousterhout is currently trying
to get a
minimal Homa implementation into the kernel.
