Network Setup is a system service that allows you to manipulate network
configurations. You can use Network Setup to read, create, modify, and delete
network configurations. Any option that is accessible to the user through the
network control panels provided by Apple is also available to you through the
Network Setup programming interface.
This chapter describes the overall Network Setup architecture and introduces
the terminology needed to understand how to use Network Setup. It assumes
that you are familiar with the existing network control panels provided by
Apple (for example, the TCP/IP control panel) from a user's perspective,
especially the configurations window used to select, duplicate, and rename
network configurations.
Network Setup Architecture 1
Prior to the introduction of Network Setup, each network protocol stack used
its own private mechanism to store preferences and make those preferences
active. Network preferences were stored as resources in files in the Preferences
folder. Figure 1-1 shows the overall network configuration architecture prior to
the introduction of Network Setup.
