HP FTAM/9000 Overview
The HP-UX Implementation of FTAM
The HP-UX Implementation of FTAM
The HP-UX implementation of FTAM is compliant with the following
standards and specifications.
• Open Systems Interconnection (OSI) Model
• ISO/IS 8571 FTAM
• Manufacturing Automation Protocol (MAP) 3.0 Application Interface
Specification
• NBS (NIST) Phase III Implementors Agreements
Additionally, HP implemented T1.3, T2.3, A1.3, and M1.3 profiles from
the NBS (NIST) Phase III Implementors Agreements.
Open Systems Interconnection (OSI)
The OSI network model defines a standardized network architecture
that supports connection-oriented communication between devices for all
vendors. Users of an OSI network can accurately anticipate how other
network nodes behave. Once a connection is established with a remote
system, exchange of data is guaranteed.
The International Standards Organization (ISO) created the OSI model
to define the actions and services of seven communication functions
known as the seven layers. Layer seven of this model is the Application
layer (the layer on which your application program sits). The interface to
the Application layer describes your view of the network; FTAM resides
in this seventh layer. The activities below layer seven concern the
internal workings of the OSI protocols and therefore, are of little concern
to an application programmer.
ISO/IS 8571 FTAM
The international standard (IS) ISO/IS 8571 defines FTAM. This
standard specifies a virtual filestore, a set of services to manipulate that
filestore, and a set of rules (protocols) that define how to use the services.
The formal title of ISO/IS 8571 is “Information Processing Systems —
Open Systems Interconnection File Transfer, Access and Management.”
