Course description and aims

A distributed system consists of numbers of computers liaising via LAN, Internet and wireless networks. This course teaches large scale distributed systems such as Web services supported by hundreds of servers and Internet-scale systems involving millions of computers. Students learn today's and coming network computing through lectures on related technologies, cases and literature.

Student learning outcomes

Students learn how today's large scale distributed systems are constructed and what algorithms and technologies support them.


Distributed systems, Internet, server-client, peer-to-peer, scale-out, logical clocks, replication, consistency models

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

This course lectures on the topics referring slides and supplemental materials.

Students will have exercise assignments about three times.
