distributes
RADIUS requests to the servers. The first incoming RADIUS request is
proxied to the first server listed, the next to the second listed and so
on, until the list is exhausted. Then it starts again at the top of the
list. If at any time a proxied request does not receive a reply from a
remote server, that server is marked as unavailable until

seconds has elapsed. Meanwhile
that request is retransmitted to the next host due to be used.
The
result of this algorithm is to distribute the load equally amongst all the
currently operational remote RADIUS servers.
