1 Introduction
The TCP/IP and OSI protocol suites will coexist in the Internet community for several years to come. As more and more OSI hosts are fielded on the Internet, the requirement for gateways between the two protocol suites becomes more pressing.
This specification describes an application layer gateway providing interoperability between the TCP/IP File Transfer Protocol (FTP) and the OSI File Transfer, Access, and Management (FTAM) protocol. The proposed application layer gateway is based on a bi-directional set of mappings between the FTP and FTAM protocols. Since the protocols have quite different command structures, the mappings between them are not one-to-one. This paper assumes knowledge of the File Transfer Protocol (FTP) [RFC 959] and the File Transfer, Access, and Management Protocol (FTAM) [ISO8571-1,2,3,4,5].
Two important goals of the mappings are to:
-
Provide FTP users with as much emulated FTP capability on an FTAM Responder as possible, and
-
Provide FTAM users with as much emulated FTAM capability on an FTP Server as possible.
Though it is anticipated that the application layer gateway will be implemented on full protocol suites of both TCP/IP and OSI, at least one implementation of such a gateway (included in the ISO Development Environment) can be configured to operate FTAM over either OSI or TCP/IP lower-layer services.
1.1 Relationship to Other Work
Ideas presented in this specification are based on lessons learned in fielding the gateway on the MILNET, operational at NCTS Washington D.C. since 1989, and on the efforts of M. A. Wallace et al.
