Abstract

This document discusses the evaluation criteria for an Internet Standard Data Link Layer protocol to be used with point-to-point links. Although many industry standard protocols and ad hoc protocols already exist for the data link layer, none are both complete and sufficiently versatile to be accepted as an Internet Standard. In preparation to designing such a protocol, the features necessary to qualify a point-to-point protocol as an Internet Standard are discussed in detail. An analysis of the strengths and weaknesses of several existing protocols on the basis of these requirements demonstrates the failure of each to address key issues.

Abstract

This document discusses the evaluation criteria for an Internet

Standard Data Link Layer protocol to be used with point-to-point

links. Although many industry standard protocols and ad hoc

protocols already exist for the data link layer, none are both

complete and sufficiently versatile to be accepted as an Internet

Standard. In preparation to designing such a protocol, the features

necessary to qualify a point-to-point protocol as an Internet

Standard are discussed in detail. An analysis of the strengths and

weaknesses of several existing protocols on the basis of these

requirements demonstrates the failure of each to address key issues.

Historical Note: This was the design requirements document dated

June 1989, which was followed for RFC-1134 through the present.

It is now published for completeness and future guidance.
