Determining Reachability and Getting Connected

This chapter describes the System Configuration reachability and connection APIs. You use the reachability API to determine if data destined for a remote host can leave the local machine. To start or stop a PPP connection, you use the connection API.

It is not necessary to have an in-depth understanding of the System Configuration architecture to determine reachability or start a PPP connection. The reachability and connection APIs provide a layer of abstraction that allows an application to make connections without worrying about the state of the network stack.
