PPP is designed for simple links which transport packets between two peers. These links provide full-duplex simultaneous bi-directional operation, and are assumed to deliver packets in order. Although PPP is not tied to a particular type of packets it transports, its most common use is the encapsulation of IP packages over Modem lines. Basically, PPP is similar to SLIP, but it has the advantages of not being limited to one type of Protocol it can transport, a configuration negotiation phase at the start of a connection (for determining connection configuration parameters automatically), and the possibility to use standardized Authentication procedures for automated login. The two authentication schemes supported by PPP are PAP and CHAP.
