TBD.
The Transparent Inter Process Communication (TIPC) protocol is
specially designed for intra cluster communication. This protocol
originates from Ericsson where it has been used in carrier grade
cluster applications for many years.
For more information about TIPC, see http://tipc.sourceforge.net.
This protocol support is also available as a module ( = code which
can be inserted in and removed from the running kernel whenever you
