FTAM PROTOCOL PDF


The File Transfer Access and Management protocol (FTAM), an ISO application protocol, offers file transfer services between client (initiator). This paper assumes knowledge of the File Transfer Protocol (FTP) [RFC] and the File Transfer, Access, and Management Protocol (FTAM) [ISO,2,3,4. FTAM is designed to help users access files on diverse systems that use compatible FTAM implementations. It is similar to FTP (File Transfer Protocol) and NFS.

FTAM has worked well as a way to bring mainframe information systems into distributed environments.

About Us and Contact Info. Data is interpreted as records and FTAM provides the virtual filestore capabilities that store record-oriented structured files. Files are transferred between systems by first establishing a connection-oriented session. All rights reserved under Pan American and International copyright conventions.

Get info about the Encyclopedia of Networking and Telecommunicatons3rd edition This simplifies recovery after the crash. FTAM is a system in which connection-oriented information about the user and the session is maintained by a server until the session is taken down.

The FTAM model defines the architecture of a hierarchical virtual file store in terms of file structure, file attributes, and the kinds of operations that can be performed on files and their attributes. FTAM has worked well as a way to bring mainframe information systems into distributed environments, but FTAM has not caught on otherwise. Vendors are left free to create their own user interfaces to FTAM file systems or use existing interfaces for their vendor-specific file systems.

FTAM is an OSI standard that provides file transfer services between client initiator and server responder systems in an open environment. In these respects, it strives to be a universal file system. It also provides access to files and management of files on diverse systems.

For example, users can lock files or lock individual records. Contribute to this site Electronic licensing info. FTAM specifies document types as files with straight binary information or text files in which each line is terminated with a carriage return.

Access file stores both locally and remotely, making FTAM a distributed file access protocol more similar to Gopher in this regard than to FTP Integrate management of both local and remote file stores, including the ability to manipulate both files and their attributes Access file stores on different kinds of machines that have different types of file systems Transfer files both synchronously and asynchronously The FTAM model pritocol the architecture of a hierarchical virtual file store in terms of file structure, file attributes, and the kinds of operations that can be performed on files and their attributes.

FTAM uses the concept of a virtual filestore, which provides a common protoco of files. In this respect, FTAM has some relational database features.

In a stateful system, both systems must be aware that one or the other has crashed so they can restore the states and prevent data corruption. The FTAM file system hides the differences between different vendor systems.

Once the session is established, file transfer can take place. FTAM enables users to: The FTAM standard does not specify the actual user interface for file access and management, simply the underlying architecture of the system. Many of the implementations so far have failed to interoperate with one another. In a stateless system, such as NFS, requests are potocol independently of one another in a connectionless manner.

There are advantages to stateless operation.

If the server crashes, the request simply goes away and the client makes another request.
