PPP

PPP is the Point-to-Point-Protocol. The successor to SLIP, PPP provides router-to-router

and host-to-network connections over both synchronous and asynchronous circuits.

PPPoA (RFC 2364)

The Point-to-Point Protocol (PPP) provides a standard method for transporting multi-

protocol data grams over point-to-point links. This document describes the use of ATM

Adaptation Layer 5 (AAL5) for framing PPP encapsulated packets.

PPPoE (RFC 2516)

This document describes how to build PPP sessions and encapsulate PPP packets over

Ethernet. PPP over Ethernet (PPPoE) provides the ability to connect a network of hosts

over a simple bridging access device to a remote Access Concentrator.

Protocol

A protocol is a set of rules for interaction agreed upon between multiple parties so that

when they interface with each other based on such a protocol, the interpretation of their

behavior is well defined and can be made objectively, without confusion or

misunderstanding.

PVC

Permanent Virtual Circuit, connection-oriented permanent leased line circuit between end-

stations on a network over a separate ATM circuit.
