Abstract

The Point-to-Point Protocol (PPP) [1] provides a standard method for

transporting multi-protocol datagrams over point-to-point links.

This document describes the use of ATM Adaptation Layer 5 (AAL5) for

framing PPP encapsulated packets.

Applicability

This specification is intended for those implementations which desire

to use the facilities which are defined for PPP, such as the Link

Control Protocol, Network-layer Control Protocols, authentication,

and compression. These capabilities require a point-to-point

relationship between the peers, and are not designed for the multi-

point relationships which are available in ATM and other multi-access

environments.

1. Introduction

ATM AAL5 protocol is designed to provide virtual connections between

end stations attached to the same network. These connections offer a

packet delivery service that includes error detection, but does not

do error correction.

Most existing implementations of PPP use ISO 3309 HDLC as a basis for

their framing [3].

When an ATM network is configured with point-to-point connections,

PPP can use AAL5 as a framing mechanism.

2. Conventions

The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD,

SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, when they appear in this

document, are to be interpreted as described in [10].

3. AAL5 Layer Service Interface

The PPP layer treats the underlying ATM AAL5 layer service as a bit-

synchronous point-to-point link. In this context, the PPP link

corresponds to an ATM AAL5 virtual connection. The virtual

connection MUST be full-duplex, point to point, and it MAY be either

dedicated (i.e. permanent, set up by provisioning) ...
