To explain that the Internet is not a specific application such as web but an information/communication infrastructure and the end to end argument, the fundamental architectural principle of the Internet, with specific protocols at transport and application layers. It is expected that participants can design network protocols with the end to end argument in mind.

Student learning outcomes

To understand what is protocol. To understand the end to end argument, the principle of the Internet and be able to explain it with specific examples. To be able to identify some protocol violating the end to end argument and its harmful consequences.

Course taught by instructors with work experience
