Introduction to the Compaq FTAM Responder | Compaq FTAM Services |
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).
FTAM file handling is defined in terms of initiator and responder functions. The initiator provides application programs with access to the FTAM protocol so that you can request services to be performed by a responder across the network. The remote responder acts as a file server and performs the requested services.
Compaq FTAM Services
Compaq FTAM provides most of the FTAM services specified in ISO 8571.
The Compaq FTAM implementation separates the initiator and responder functions into two processes. The Compaq FTAM initiator process implements the initiator function, while the Compaq FTAM responder process implements the responder function.
Note. The initiator and responder functions of remote FTAM implementations are not necessarily performed by separate processes. In this manual, the term “remote initiator” refers to the entity in the remote implementation that performs the initiator function.
The initiator and responder processes provide the FTAM functions required for your applications. These processes manage the FTAM communications among your application and other FTAM applications on the local or remote computer systems on an OSI network.
Compaq FTAM can handle the following types of files, where the corresponding FTAM document types are listed parenthetically:
•
•
•
•
Unstructured text files
FTAM Applications
This manual focuses on the FTAM services available to remote ISO FTAM applications through the Compaq FTAM responder. There is no programmatic interface to the Compaq responder; you request the services of the responder by means of the FTAM interface on your remote system, which may or may not be a Compaq system.
ISO FTAM protocol defines a common model of the file system (the virtual filestore, described later in the manual), which allows all computer systems on an open network to share the same
