EE450/550: Principles of Networking


Telecommunication networks play a key role in the development of our society. The remote interconnection of all types of devices, ranging from personal computers, cellphones and tablets, to data centers or distributed sensors, are at the basis of many of our daily activities. In this course, the fundamental concepts of telecommunication networks will be introduced. A bottom-up layered approach will be used to explain how the performance requirements of telecommunication networks have been traditionally solved. In particular, the functionalities of the physical layer, e.g., information modulation, coding and transmission; data link layer, e.g., medium access control, error control and addressing; network layer, e.g., information routing and forwarding; transport layer, e.g., end-to-end reliable transport and QoS provisioning, and application layer, will be discussed in detail. In addition to the theoretical lectures, guided experimental assignments with advanced network simulation and monitoring tools will be conducted to better illustrate the concepts learnt in the class. This course will provide the students with the necessary knowledge to understand current data communication networks as well as to contribute to the development of next generation telecommunication systems.

Objectives and Expected Outcomes

  • Identify and describe the main network functionalities at each layer of the protocol stack
  • Identify and describe different communication solutions and the most common protocols in telecommunication networks
  • Analyze and interpret packet traffic from real telecommunication networks by means of software monitoring tools
  • Design and simulate simple network architectures by means of software simulation tools
  • Recognize and describe common telecommunication standards and standardization entities
