Students acquire an understanding of the differences between TCP and UDP (connection-oriented vs. connection-less) data transfers as they analyze network packet data collected during one of a series of labs designed for an introductory network essentials course taught at Boise State University. The learning emphasis of the lab is not on the capture of the data, but instead on the analysis that follows. By assisting students in developing techniques to filter large batches of data using open-source tools, they gain considerable insight into the differences between aforementioned protocols.
