Internetworking

Aim

The aim of the course is to give knowledge about internetworking technologies, focusing on the Internet. After completing the course, the student is expected to be able to:

• Explain how an internet works, which different components are included and why they are included.
• Give an account of how Internet works on protocol level, what protocols are used, and what functionality these protocols contribute with.
• Explain how optical fibers, optical components and optical transmitters, amplifiers and receivers work.
• Explain how optical fiber communication systems work, and their application in the core and access networks of Internet.
• Describe basic principles of source and channel coding for packet networks, special networks for clouds and Internet-of-things.
• Perform a simple economic analysis for ISP:s.
• Set up a local Ethernet network and analyse the traffic in this network.
