Entry requirements
Note: Admission requirements for non-programme students usually also include admission requirements for the programme and threshold requirements for progression within the programme, or corresponding.
Prerequisites
Knowledge of C or C++ are required in order to be able to do the laborations in the course. It is an advantage if the student also has knowledge corresponding to Concurrent Programming and Operating Systems, especially know how to explain the resource conflicts that can occur in a computer program and how to solve them. This knowledge can, however, be acquired while doing the laborations in the course. The student is also assumed to know how to construct and test programs in a Unix/Solaris environment.Intended learning outcomes
After the course, you are expected to be able to:
- Explain, describe, and analyze a typical network architecture, including the importance of network layers and encapsulation
- Explain the different basic types of protocols, communication channels, and network types
- Design, implement, verify, and test your own protocols
- Explain fundamental performance tradeoffs, including showing an understanding of where delays can occur in a network, what different types of delay that exist, the impact of packet losses and jitter on various protocols
- Describe and analyze the most common application architectures in the Internet, how the most important application-layer protocols work, the service they provide, as well as have the ability to design and implement their own application-layer protocols
- Analyze and explain important design considerations at the transport layer, including hands-on knowledge of how flow control and congestion control works, and how reliable data transfer is implemented
- Motivate and explain how routing and forwarding is implemented on the Internet, including the design and implementation of network-layer protocols
- Describe and explain different link-layer technologies and how they work
- Network security: Exemplify how different types of security services can be implemented in different layers with the help of different standards
- Wireless and mobile networks: Analyze and exemplify some of the unique challenges as we are moving towards increasingly mobile users
- Multimedia networking: Explain and discuss the fundamentals of how multimedia services are provided over the Internet

Regulations (apply to LiU in its entirety)
The university is a government agency whose operations are regulated by legislation and ordinances, which include the Higher Education Act and the Higher Education Ordinance. In addition to legislation and ordinances, operations are subject to several policy documents. The Linköping University rule book collects currently valid decisions of a regulatory nature taken by the university board, the vice-chancellor and faculty/department boards.
LiU’s rule book for education at first-cycle and second-cycle levels is available at http://styrdokument.liu.se/Regelsamling/Innehall/Utbildning_pa_grund-_och_avancerad_niva.
