How network selection works

The network selection component is built around:

• A network configuration database (the /etc/netconfig file) that contains an entry for each network on the system.

• An optional NETPATH environment variable, set by a user and containing an ordered list of network identifiers. These network identifiers match the netconfig ``network ID'' field and are used as links to the records in the netconfig file.

• A network selection application programming interface. The interface consists of a set of network configuration database access routines.
