Abstract

The Point-to-Point Protocol (PPP) [1] provides a standard method for transporting multi-protocol datagrams over point-to-point links. PPP defines an extensible Link Control Protocol, and proposes a family of Network Control Protocols for establishing and configuring different network-layer protocols.

This document describes a new Network level protocol (from the PPP point of view), PPP Serial Data Transport Protocol, that provides encapsulation and an associated control protocol for transporting serial data streams over a PPP link. This protocol was developed for the purpose of using PPP’s many features to provide a standard method for synchronous data compression. The encapsulation uses a header structure based on that of the ITU-T Recommendation V.120 [2].

1. Introduction

This document is a product of the TR30.1 ad hoc committee on compression of synchronous data. It represents a component of a proposal to use PPP to provide compression of synchronous data in DSU/CSUs.

In addition to providing support for multi-protocol datagrams, the Point-to-Point Protocol (PPP) [1] has defined an effective and robust negotiating mechanism that can be used on point to point links. When used in conjunction with the PPP Compression Control Protocol [3] and one of the PPP Compression Protocols [4-10], PPP provides an interoperable method of employing data compression on a point-to- point link.
