Introduction to NonStop OSI/FTAM

This manual describes the NonStop Open Systems Interconnection/File Transfer,

Access and Management (OSI/FTAM) product used in developing FTAM applications.

NonStop OSI/FTAM is the NonStop implementation of the FTAM standard ISO 8571,

developed by the International Organization for Standardization (ISO).

File Transfer, Access and Management (FTAM) is a set of Application Layer services

and an Application Layer protocol to support file handling on Open Systems

Interconnection (OSI) networks. Using this standard FTAM protocol across an OSI

network, different computer systems can transmit and receive file contents and

file-management-related messages.

While this manual is designed to be as complete as possible with regard to the

NonStop FTAM implementation, it is not intended to duplicate or replace the ISO

standards and National Institute of Science and Technology (NIST) FTAM Phase 2

agreements. About This Manual lists the relevant ISO and NIST documents that you

might want to review.

In this manual, ISO FTAM refers to the FTAM specification as defined in ISO 8571, and

NonStop FTAM refers to the NonStop OSI/FTAM product.

This section covers the following topics:

Functional Overview

ISO FTAM provides the following file-handling functions across the network:

•

Creating files

•

Deleting files

•

Erasing part or all the contents of files

•

Reading from files

•

Writing to files

•

Reading file attributes

•

Changing file attributes

FTAM users communicate with the FTAM service provider by way of primitives, the

smallest units of interaction between the FTAM user and the FTAM service provider. An

operation like any of those mentioned above requires the exchange of multiple

primitives, which the FTAM software encodes as protocol data units (PDUs), the
