Course description and aims

Basic theories and principles of information and communication networks are lectured on including data communication protocols, circuit and packet switching, and networking. And, performance analysis methods are studied including protocol analysis methods and queueing theory (teletraffic theory) based on a probabilistic approach.

Student learning outcomes

By the end of this course, students will be able to:
1. understand network architecture;
2. design data communication protocols;
3. design media access protocols;
4. design switching and exchanging systems by using queueing theory;
5. design network systems by using queueing theory
