Syllabus
Course overview and goals
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 physical, datalink and network layers. It is expected that participants can design network protocols with the end to end argument in mind.
Course description and aims
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 protocols violating the end to end argument and its harmful consequences.
Student learning outcomes
実務経験と講義内容との関連 (又は実践的教育内容)
As a side job, acted as a technical advisor of Softbank, a CTO of Mobile Internet Services Inc. etc. to construct and operate the Internet. Acted as an editor/author of rfc1995 etc., involved in developing various internet protocol standards in IETF. Ecomonic background of Internet technologies are often explained.
Keywords
End to end argument, Internet, Architecture, Layering, Catenet Model
Competencies
- Specialist skills
- Intercultural skills
- Communication skills
- Critical thinking skills
- Practical and/or problem-solving skills
- With various protocols, why they succeeded or failed is explained in theory and practice technically and/or economically.
Class flow
Lecture on each topic with questions and comments from the participants. The participants are required to ask a question or make a comment on the lecture at least twice during a term of the course.
