FTP-FTAM Gateway Specification
Status of the Memo
This RFC specifies an IAB standards track protocol for the Internet
community, and requests discussion and suggestions for improvements.
Please refer to the current edition of the "IAB Official Protocol
Standards" for the standardization state and status of this protocol.
Distribution of this memo is unlimited.
Abstract
This memo describes a dual protocol stack application layer gateway
that performs protocol translation, in an interactive environment,
between the FTP and FTAM file transfer protocols.
Two key assumptions are made: 1) POSIX file naming conventions and
hierarchical organization, rather than proprietary conventions are in
use; and 2) X.500 Directory Services are available.
Acknowledgments
The authors of this RFC would like to express their appreciation to
the individuals and organizations that participated in the
implementation of the FTP-FTAM Application Layer Gateway and its
fielding on the MILNET. Implementation credits go to Mr. John Scott,
formerly of the MITRE Corporation, while fielding credits are
extended to James Graham and R. Greg Lavender of Open Networks, Inc.
(formerly NetWorks One) and Robert Cooney of the Naval Computer and
Telecommunications Station (NCTS) Washington. Dr. Marshall Rose is
to be commended for recognizing the importance of the FTP-FTAM
gateway and promulgating it as a part of the ISO Development
Environment (ISODE). The following individuals have provided
valuable editorial comments: Larry Friedman, Donna Vincent and
Michael Resnick of Digital Equipment Corporation; Robert Cooney of
NCTS; and S.E. Hardcastle-Kille of University College London. Funding
of the FTP-FTAM Gateway Request for Comments effort was provided by
Open Networks Inc. and the Defense Information Systems Agency (DISA),
formerly the Defense Communications Agency. DISA sponsors include
Len Tabacchi, George Bradshaw, Tom Clarke, and Betsy Turner.
