Large, complex, feature-rich network architecture developed in the 1970's by IBM. Similar in some respects to the OSI reference model, but with a number of differences. SNA is essentially composed of seven layers.
Systems Network Architecture. A comprehensive specification for distributed data processing developed by IBM in 1974. SNA defines rules, procedures, and a layered protocol for communication and control within a network.
Systems Network Architecture. 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.
Systems Network Architecture. Set of seven-layered protocols developed by IBM to connect mainframe computers. Dependent on the fundamental protocol synchronous data link control (SDLC).
Systems Network Architecture. A widely used communications framework developed by IBM to define network functions and to establish standards for enabling its different models of computers to exchange and process data. SNA contains separate layers. As changes occur in one layer, no other layer need be changed. An IBM-developed layered network architecture that isolates applications from system network services, so developers can write applications independent of the lower-level networking software layers.
(Systems Network Architecture) A network architecture developed by IBM.
Systems Network Architecture. 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
acronym for Systems Network Architecture, a large scale networking protocol invented by IBM
Systems Network Architecture. An earlier network technology that was developed by IBM.
Systems Network Architecture. IBM mainframe protocol designed to run over IBM's token ring architecture. Needlessly to say, nobody uses it.
IBM's System Network Architecture. Similar to the Digital Network, it provides a common method of support for a wide range of communication activities sharing a single communications network. SNA is composed of three elements: Virtual Telecommunication Access Method (VTAM), Network Control Program/Virtual Storage (NCP/VS) and Synchronous Data Link Control (SDLC). Compare with: DNA (Digital Network Architecture).
System Network Architecture (introduced in 1973). Developed by IBM.
Systems Network Architecture. A proprietary network architecture used in IBM systems to connect terminals to a mainframe.
Systems Network Architecture. Large, complex, feature-rich network architecture developed in the 1970s by IBM. SNA is essentially composed of seven layers.
Systems Network Architecture. 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.
System Network Architecture. Enterprise communications standard developed by IBM for linking different systems running IBM operating systems such as OS/400 (AS/400), OS/2 (PC), AIX (RS/6000), etc.
Systems Network Architecture. IBM's proprietary cross-platform telecommunications architecture.
Systems Network Architecture. 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
Systems Network Architecture The IBM SNA communications world ls host-centric and relies largely on dedicated lines for connecting the main computer center with remote terminals. A classic configuration would depicted a mainframe, channel-attached to a Front-End Processor (FEP). These FEPs are connected to terminal controllers via dedicated lines. Most users have migrated their traffic from dedicated analog lines to dedicated digital lines because of the superior transmission performance and reliability. (7/96)
Systems Network Architecture. A network developed by IBM to interconnect IBM's family of computers.
System Network Architecture. A proprietary network architecture designed by IBM. It uses seven layers, like the OSI model, but unlike the OSI model it uses a standard protocol for each layer.
Systems Network Architecture (IBM's primary networking strategy made up of a variety of interacting hardware and software products)
System Network Architecture. IBM's network architecture that allows connecting LAN systems to IBM mainframe computers.
Systems Network Architecture. It is an architecture created by IBM, where the logical channels are created between terminals.
IBM Systems Network Architecture Mainframe-centric hierarchical communication protocol.
Systems Network Architecture. IBM's layered protocols for mainframe communications.
Systems Network Architecture. 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.
Systems Network 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.
Systems Network Architecture is a proprietary IBM architecture for network computing within an enterprise. With the advent of multi-enterprise network computing, the Internet, and TCP/IP, IBM is finding ways to combine its own SNA within the enterprise with TCP/IP for applications in the larger network.

Systems Network Architecture. An architecture, including specifications for the logical structure, formats, protocols and operational sequences for transmitting informtion through, and controlling the configuration and operations of networks.
(1) IBM's standardized relationship between its VTAM and the NCP. (2) SNA specifies how products connect and communicate with one another in a network. SNA is a design for a total data communication system, encompassing every part of the communication network from the user's application program at the central site to the terminal at a remote location possible hundreds of miles away. SNA itself is not a system; it is an architecture. The purpose of SNA is to define uniform formats and protocols for data communication networks.
Systems network architecture. Networking protocol popular in IBM environments.
A communications protocol describing a terminal-to-mainframe type connection.
