Systems Network Architecture
<networking> (SNA) IBM's proprietary high level networking protocol standard, used by IBM and IBM compatible mainframes. Also referred to as "Blue Glue", SNA is a bletcherous protocol once widely favoured at commercial shops. The official IBM definition is "that which binds blue boxes together." It may be relevant that Blue Glue is also a 3M product commonly used to hold down carpets in dinosaur pens. [Jargon File] (1994-11-23) | ||||

IBM Systems Network Architecture
Systems Network Architecture (SNA) is IBM's proprietary networking architecture created in 1974. It is a complete protocol stack for interconnecting computers and their resources. SNA describes the protocol and is, in itself, not actually a program. The implementation of SNA takes the form of various communications packages, most notably VTAM which is the mainframe package for SNA communications. SNA is still used extensively in banks and other financial transaction networks, as well as in many government agencies. While IBM is still providing support for SNA, one of the primary pieces of hardware, the 3745/3746 communications controller has been withdrawn from marketing by the IBM Corporation. However, there are an estimated 20,000 of these controllers installed and IBM continues to provide hardware maintenance service and micro code features to support users. A robust market of smaller companies continues to provide the 3745/3746, features, parts and service. The VTAM telecommunications access method is also supported by IBM, as is the IBM Network Control Program (NCP) required by the 3745/3746 controllers.
