Point-to-Point Protocol
(PPP)
Introduction
Point-To-Point Protocol 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. PPP is intended to provide a common solution for
easy connection for a wide variety of hosts, bridges and routes.
In the process of configuring, maintaining and terminating the
point-to-point link, PPP goes through several distinct phases which
are specified in the following simplified state diagram:
