PPP in Frame Relay

Status of this Memo

This document specifies an Internet standards track protocol for

the Internet community, and requests discussion and suggestions for

improvements. Please refer to the current edition of the "Internet

Official Protocol Standards" (STD 1) for the standardization state

and status of this protocol. Distribution of this memo is unlimited.

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 Frame Relay for framing PPP

encapsulated packets.

Applicability

This specification is intended for those implementations which desire

to use 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 peers, and are not designed for multi-point or

multi-access environments.

1. Introduction

Frame Relay [2] is a relative newcomer to the serial link community.

Like X.25, the protocol was designed to provide virtual circuits for

connections between stations attached to the same Frame Relay

network. The improvement over X.25 is that Q.922 is restricted to

delivery of packets, and dispenses with sequencing and flow control,

simplifying the service immensely.

PPP uses ISO 3309 HDLC as a basis for its framing [3].
