This laboratory course provides students with hands-on training and experience regarding the design, implementation, and packet inspection of computer networks. Students experiment with network simulation and packet tracing tools. Topics covered in experiments include: network addressing, address resolution protocol (ARP), Dynamic Host Configuration Protocol (DHCP), troubleshooting tools (e.g., ipconfig, traceroute, ping), basic networks simulation, server configuration at application layer, basic switch set-up and configuration, trunking in virtual local area networks (LAN), router setup and configuration in LAN and wide area networks (WAN), static and dynamic routing.
