Abstract

The PPP Working group has developed two protocols, one to control compression on PPP links; the Compression Control Protocol (CCP), documented in draft-ietf-pppext-compression-04.txt. The second is the Encryption Control Protocol (ECP), used to control encryption on serial links, documented in draft-ietf-pppext-encryption-03.txt. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.

1. Variance

1.1. The Problem

1.1.1. History

The PPP Working group has developed two protocols, one to control compression on PPP links; the Compression Control Protocol (CCP), documented in draft-ietf-pppext-compression-04.txt. The second is the Encryption Control Protocol (ECP), used to control encryption on serial links, documented in draft-ietf-pppext-encryption-03.txt. During the development of these protocols, the Motorola Corporation informed the IETF that they may infringe on certain patents held by Motorola, specificlally U.S. patents 5,245,614 and 5,130,993.

RFC 1915 PPP ECP and CCP Variance February 1996

After development of the protocols was completed, they were submitted to the IESG for standardization. At this point, because of the outstanding patent claims, their progress was halted. Per the procedures of RFC 1602, the IESG Secretariat attempted to gain the licenses required by RFC 1602. In particular, per section 5.6 of RFC 1602, an attempt was made to acquire a form of the license and make it publically available via the Internet.

Motorola would prefer to provide a general statement indicating that licenses will be made available "to any party under reasonable terms and conditions that are demonstrably free of unfair discrimination."

1.1.2. Other Attempted Solutions

An attempt was made to have the PPP working group develop revised versions of CCP and ECP that would not infringe on the patents. While technically possible, the proposed technical changes are viewed by some members of the working group as much less technically desireable than the original CCP and ECP and, in fact, these members have stated quite clearly that they will implement the original CCP regardless of the protocol standardized by the working group or accepted by the IESG....
