RE: How partitions talk on the same machine

Question

All,
Partitions on the same physical node will use Domain (Berkeley) sockets
when available, to avoid the "seven layer salad". If not available,
messages between partitions will dive through the mayonaise, bacon,
lettuce, etc, and use the full TCP/IP stack.
From a tech note: "When a Unix Domain socket is created, a file in theformat of
FORTE_0000XXXX, where XXXX is the process id in hex, is placed in the
directory %{FORTE_ROOT}/tmp. If FORTE_ROOT is not set, this file will be
placed in /tmp instead. This is a good place to look to see if a process
is listening on an Unix Domain socket."

Subject: How partitions talk on the same machine
Does anyone know how partitions on the same Unix machine communicate? Do
they use internal TCP/IP or do they actually go out on the network and
do a loop back?
I'm assuming that Forte uses the network to find the partition via the
Name Service/Environment Manager (once) and once it finds the partition,
Forte uses internal TCP/IP to talk process to process.
