Development and Evaluation of Visualization Tools for Understanding the Control Method of TCP Packet Arrival Order and the Difference between TCP and UDP

This paper describes the design, implementation, and evaluation of visualization tools for understanding the control method of TCP packet arrival order and the difference between TCP and UDP. TCP/IP protocols have grown to be the fundamental technology for computer networks and the Internet. As a result, communication and computer engineers have to learn these protocols. This paper examines the problems in the TCP/IP course and proposes two tools to solve these problems. The first tool is to help with learning the control method of TCP packet arrival order. The second tool is for learning the differences between TCP and UDP. The two tools have a packet capturing function and can display real communication data without any special hardware. Evaluation results show that the tools are effective for learning the protocols.
