Simulation-Based Learning via Cisco Packet Tracer to Enhance the Teaching of Computer Networks

Abstract

Teaching and learning computer networks is a crucial part of a computing undergraduates' education. However, it is an abstract topic with theory that can be challenging for students to comprehend. Simulation-based learning can be used as a teaching tool to enhance networking-based lecture topics and help students more easily understand and visualise how it really works in a safe, user-friendly environment. One such simulation tool, Cisco Packet Tracer, can be used to good effect, and this paper reports on the practical implementation of the tool as identified in existing literature. Additionally, this paper discusses how Packet Tracer was utilised as part of a UK based first year undergraduate module 'Computers and Security', and details the content of nine practical sessions, whilst also identifying the main benefits and challenges of their implementation from a practitioner's perspective. It was found that while Packet Tracer can be an additional benefit to augment the teaching of networking concepts, there are limitations and challenges which educators must be aware of if implementing the tool. The paper therefore concludes with providing recommendations which should help educators and curriculum designers in creating and delivering more effective and interactive networking sessions.

“…Other learning models using Packet Tracer (Vijayalakshmi, Desai & Raikar, 2016;Zhang, Liang & Ma, 2012;Janitor, Jakab & Kniewald, 2010) offer basic introductions and application/transport layer exercises but neglect crucial network and link layer aspects. Further limitations can be observed in models focusing solely on router configuration via device commands (Javid, 2014;Noor, et al, 2018), or topics like Internet of Things (IoT) simulation (Gwangwava & Mubvirwi, 2021;Almalki, 2020;Chaudhari, Joshi, Joshi & Kumar, 2020;Gumina & Tang, 2021), or basic routing table manipulation, wireless, and firewall configurations (Allison, 2022;Abdrabou & Shakhatreh, 2021;Reddy, et. al, 2020).…”

The use of TAM in evaluating the effectiveness of network simulation tools in Internet Technologies subject

“…Packet Tracer software has been used around the globe to enhance students learning. Especially during the COVID-19 pandemic (Allison, 2022). A recent review of the literature found that, since the outbreak of the pandemic, more and more institutions have adopted PT as a teaching tool to foster remote learning.…”

“…A study conducted in Malaysia by Allison (2022) developed a Survey on the Challenges Faced by the Lecturers in Using PT in Computer Networking Courses. Their idea was to identify the problems faced by teachers throughout the teaching and learning process, even with the help of instructional simulations.…”

“…TAM is a useful theoretical model for predicting how technology or a system is used and its effectiveness (Isaac et al, 2018). According to Allison (2022), TAM is a widely accepted concept that explains the relationships between users and technology. It is based on the notion that users' attitudes towards technology are based on their beliefs regarding the utility and convenience of the technology.…”

Determinants of Intention to Use Simulation-Based Learning in Computers and Networking Courses: An ISM and MICMAC Analysis

“…Due to advancements in technology in higher education settings, the significance of computer networks is amplified. Computer networks aid in seamless communication, network infrastructures, data transfer, and collaboration across devices, systems, and users [2]. The traditional methods of teaching in higher education for computer networking frequently encounter challenges in providing a comprehensive understanding of complex networking concepts to learners [3].…”
