Systems Network Architecture

Systems Network Architecture[1] (SNA) is IBM's proprietary networking architecture, created in 1974.[2] It is a complete protocol stack for interconnecting computers and their resources. SNA describes formats and protocols but, in itself, is not a piece of software. The implementation of SNA takes the form of various communications packages, most notably Virtual Telecommunications Access Method (VTAM), the mainframe software package for SNA communications.
