The repeater is a *client* side thing, as it fans out incoming beacons
from other CA servers to local CA clients.

In the "ca" directory (that has the ChannelAccess client code), the
constructor of the udpiiu class (in udpiiu.cpp) calls
caStartRepeaterIfNotInstalled(), which spawns off the repeater (around
line 590 in udpiiu.c).
There, depending on the architecture, the repeater is started as a
process or (if not supported) as a thread.

It is the old C Channel Access server. "srv" is for "server", I don't
know what the "r" is for.

Hope this helps,
