Abstract:
Abstract- The TCP/UDP/IP/Ethernet protocol suite is commonly covered within an undergraduate curriculum. Often, this is the first exposure students have to a network protocol. We have found that students have difficulty understanding the unique functions of these protocols and how the protocols are related. This is due at least in part to the fact that packet specification and construction takes place within the operating system, while covering a typical operating system protocol stack implementation would be beyond the scope or time constraints of many of these undergraduate courses. In order to address this problem, we have written a visualization tool that illustrates the operation of TCP and UDP over the IP and Ethernet protocols using real packets captured live from the network or stored in a file. The tool provides several views of captured data that, when used individually or in combination, illustrate the operation of these protocols. Index terms- Network protocols, visualization, socket programming
