DNS configuration
This configuration relies on the DNS server to cause incoming connection
requests to be distributed among the NIFs. For example, a round-robin DNS
system can be employed. The example shown in Figure F-4 makes use of a
DNS server that will give a different IP address for HOST1 on each name
lookup. The first workstation that connects uses10.1.90.20, the second uses
10.1.90.21, and so on.
If a round-robin DNS system is not available, the individual workstations need
to be configured to connect to specific NIFs on the host by using the
[RESOLVER] section (see the text at the bottom of Figure F-5). This
configuration is more complicated but does not severely reduce the throughput
and availability, because the [RESOLVER] entry for a host can give multiple IP
addresses for that host in order to handle the contingency that the first listed IP
address cannot be used (for example due to a network-adapter failure on the
host).
