Brief Course Description

This course introduces basic elements of modern computer and telecommunication networks. A hybrid five-layer reference model resembling the popular TCP/IP model will be discussed. In each layer, the state-of-the-art hardware and software technologies are introduced. These include, for example, Fiber-optic and Mobile/Cellular communications in the Physical Layer; Wavelength/Time Division Multiple Access Protocols in the Data Link Layer; Unicast and Multicast protocols in the Network Layer; TCP/UDP and ATM Adaptation Layer Protocols in the Transport Layer; and Network Security in the Application Layer.
