About Network Setup

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

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.
