1. The part of a user-application network that conforms to the formats and protocols of SNA. It enables reliable transfer of data among end users and provides protocols for controlling the resources of various network configurations. The SNA network consists of network accessible units (NAUs), boundary function, gateway function, and intermediate session routing function components; and the transport network. 2. (IRM) The framework, designed by IBM, which defines the structuring of data communications functions and protocols of the mainframe, including networking protocols, administration software, and hardware devices that provide physical delivery of those protocols.
A description of the logical structure, formats, protocols, and operation sequences that transmit information and that control the configuration and operation of an IBM network.
IBM's proprietary cross-platform telecommunications architecture.
In IBM networks, the description of the layered logical structure, formats, protocols, and operational sequences that are used for transmitting information units through networks, as well as controlling the configuration and operation of networks.
A proprietary networking architecture used by IBM and IBM- compatible mainframe computers.
A comprehensive specification for distributed data processing developed by IBM. SNA defines a layered protocol for communicating and controlling a communications network within the IBM environment.
Set of seven-layered protocols developed by IBM to connect mainframe computers. Dependent on the fundamental protocol synchronous data link control (SDLC).
An architecture that describes the logical structure, formats, protocols, and operational sequences for transmitting information units through the networks and also the operational sequences for controlling the configuration and operation of networks.
A communications framework developed by IBM to define network functions and establish standards for enabling computers to share and process data.
IBM's design for wide area networks in which data communications system functions are separated into three discrete areas: the Application layer, the Function Management layer, and the Transmission Subsystem layer. SNA is a de facto standard that includes a peer-to-peer protocol called Advanced Program to Program Communications (APPC), and is supported by many computer vendors. Go Top
The total description of the logical structure, formats, protocols, and operational sequences for transmitting information units through, and controlling the operation of, networks. The structure of SNA permits the end user to be independent of, and unaffected by, the specific facilities used for information exchange.
IBM mainframe network standards. Originally a centralised architecture with a host computer controlling many terminals, enhancements, such as APPC (LU 6.2), have adapted SNA to today's peer-to-peer communications and distributed computing environment
A family of protocols used to connect IBM mainframes with workstations and other remote devices. SNA specifies the roles of the different kinds of remote devices--logical unit (LU) types such as display stations--and the rules under which data passes between devices and a mainframe. See also logical unit, physical unit, system services control point.
