Content and learning outcomes

Course contents

The course spans over the functions in a communication system from transmission of data over a link to network services and applications and system architecture that organizes the functions in protocols. The course intends to give understanding and application of design principles of software engineering and overview of underlying system principles, communication technologies and considerable standardized systems. 

The parts of the course are: 

  • Data communication and data links
  • Networks with many links
  • Transport and applications
  • System architecture

Intended learning outcomes

After passing the course, the student should be able to

  • explain principles and parts of system architectures for networks and describe system functions in the architecture that is necessary for functioning network summarise and explain how networks in whole function
  • explain, calculate and discuss data communication and data links for both point-to-point and shared links describe necessary functions for links with correct descriptions and to carry out calculations of capacity, error handling and throughput 
  • explain network structures and principles of addressing and routing with correct terminology and distinguish and discuss networks on data link network layer carry out routing calculations and describe protocols for packet switching
  • explain and illustrate the concepts of application and service and describe the function of given systems and user applications explain the functions in transport protocol for reliable transfer rightly descriptions and apply them on selected problems

in order to obtain an overview of the function of communication networks and a good basis for continued studies of the subject.
