The lecture gives an introduction to fundamental concepts and mechanisms of digital communication networks. After explanation of some basic terms we first introduce hierarchical structuring of networks leading to the OSI reference model. Subsequent to discussion of data transmission from point to point, data link protocols for error-free transmission are discussed, especially forward error control and ARQ protocols. Protocols for multiple access control follow, among them ALOHA protocols, strategies to detect and resolve collisions, carrier sensing, as well as token passing principles. Subsequently, fundamental routing algorithms are explained. After an introduction into queuing theory, the lecture gives an overview of the internet protocol suite TCP/IP as important system example and closes with an analysis of multimedia networks.
