Chapter 1. A layered model of data-communications 1.0. Abstract. Telecommunications systems can be extremely complex. In order to keep that complexity under control it is necessary to subdivide the systems into a certain number of subsystems, which are as independent from each other as possible. Starting with SNA, announced by IBM in the early seventies, computer networks have systematically been designed as a set of independent functional layers. The principle of such decomposition
