This week was the first week of CST311 Introduction to Computer Networks. This first week served as an introduction to how the internet works and was a prep week for us to install all of the software needed to complete the programming assignments. We learned about the concepts of delay, loss and throughput in regards to internet data transfer. We also got an introduction to Mininet and Wireshark which are the programs we will utilize to build and test our simulated virtual network. I am excited to learn more about computer networks and how they function 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.
