The week we continued learning about computer networks and focused on the application layer. We also had some practice with HTTP protocols and used Wireshark to continue to analyze the network calls. We performed a lab with Wireshark that had us analyse different types of requests, including simple text, larger text files and requests that included both text and images. I found it interesting to see how the network handled the different types of request. I look forward to learning more about computer networks in the coming weeks.
This week, we developed a deeper understanding of the network control plane and explored routing algorithms such as Dijkstra and Bellman-Ford, focusing on how they determine the most efficient paths for data transfer. We also learned about the SDN control plane, which allows for dynamic network management and routing. In addition to the theory learned this week, we conducted a network lab exploring the use of a basic SDN controller using Mininet and Wireshark. We looked at how Internet Control Message Protocol (ICMP), can be used for network diagnostics, particularly for network troubleshooting with tools like ping and traceroute.
