Echo function for ISO 8473
RFC 1139, “Echo function for ISO 8473”, is a Proposed Standard document published in January 1990 by R.A. Hagens. It has been obsoleted by RFC 1574, RFC 1575 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This memo defines an echo function for the connection-less network layer protocol. Two mechanisms are introduced that may be used to implement the echo function. The first mechanism is recommended as an interim solution for the Internet community. The second mechanism will be progressed to the ANSI X3S3.3 working group for consideration as a work item. When an ISO standard is adopted that provides functionality similar to that described by this memo, then this memo will become obsolete and superceded by the ISO standard. This memo is not intended to compete with an ISO standard. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
