2 Description of the problem Internet protocols form the basis of data communication education Motivation Internet protocols are actively studied by researchers. There are almost no tools available for studying the behavior of real network protocols Provide a tool that students can use at home, teachers can use in the classroom, and researchers can use in the laboratory Features: easy to use, powerful for visualizing, and extensible for future projects DaCoPAn Software Engineering Project University of Helsinki Petrozavodsk State University Проект DaCoPAn Университет Хельсинки Петрозаводский Государственный Университет

3 Traditional methods for teaching protocols DaCoPAn Software Engineering Project University of Helsinki Petrozavodsk State University Проект DaCoPAn Университет Хельсинки Петрозаводский Государственный Университет

4 Description of the solution Take a network with two computers Run a program called "tcpdump" This program saves the network traffic into two files Take these files, and analyze them, to see what messages happen between the two computers A file is output from the analyzer This file acts as input for the animator.

5 Uses for DaCoPAn Teachers can use scenarios to show the most important ideas. Teaching Save time preparing lectures. DaCoPAn Software Engineering Project University of Helsinki Petrozavodsk State University Проект DaCoPAn Университет Хельсинки Петрозаводский Государственный Университет Can download DaCoPAn for home use. Students Used as personal e-learning tool. Can use the tool to assign exercises to the students. Can use real data to see complex situations in a network Researchers Useful for performance analysis
