This section introduces PPP configurations. The section also defines terms that are used in this guide.
Solaris PPP 4.0 supports a number of configurations.
Switched-access, or dial-up, configurations
Hardwired, or leased-line configurations
Figure 1-1 Parts of the PPP Link
The previous figure shows a basic PPP link. The link has the following parts:
Two machines, usually in separate physical locations, called peers. A peer could be a personal computer, engineering workstation, large server, or even a commercial router, depending on a site's requirements.
Serial interface on each peer. On Oracle Solaris machines, this interface could be cua, hihp, or other interface, depending on whether you configure asynchronous or synchronous PPP.
Physical link, such as a serial cable, a modem connection, or a leased line from a network provider, such as a T1 or T3 line.
