SCTP is connection based - we have many dependencies on our connectionless
datagram model.

Todd Rimmer
Then use SCTP instead of UDP, which already provides a loss-less reliable
interface.
If SCTP has problems with the number of endpoints it can currently
support,
why not just fix that problem and fix IpoIB to use a connected model to
increase performance, rather than inventing a completly new protocol
and/or
address family.
Just a thought.
