Course Aim: 

Build an understanding of transmission and switching concepts in data communication

networks

Relate the presented concepts with practical constituents of real-life networks

Enhance the student capabilities to understand and build simulation and analytical models for the benefit of quantitative performance assessment of networks and network components (i.e., switches)
