Point-to-Point Protocol PPP | ZyXEL Communications omni series

7 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 routers.

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:
