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.

RFC

Request for Comments. The document series, begun in 1969, which describes

the Internet suite of protocols and related experiments. Not all RFCs describe

Internet standards, but all Internet standards are written up as RFCs.

RFC 1483

Multi-protocol encapsulation over AAL-5. Two encapsulation methods for carrying

network interconnect traffic over ATM AAL-5. The first method allows multiplexing

of multiple protocols over a single ATM virtual circuit. The protocol of a carried

PDU is identified by prefixing the PDU by an IEEE 802.2 Logical Link Control

(LLC) header. This method is in the following called "LLC Encapsulation". The

second method does higher-layer protocol multiplexing implicitly by ATM Virtual

Circuits (VCs). It is in the following called "VC Based Multiplexing".
