A variety of idealized models of communication systems exist, and all may have something in common. Starting with Shannon's communication model and ending with the seven layers OSI model, this paper presents progressively more advanced forms of modeling of communication systems by tying communication models together on the basis of the notion of flow. The communication system is divided into different spheres (sources, channels, and destinations), each with its own five interior stages: receiving, processing, creating, releasing, and communicating information. The flow of information is ontologically distinguished from the flow of physical signals. Accordingly, Shannon's and network-based OSI models are redesigned.
