Design and Implementation of a Network Monitoring System for Enterprise Local Networks Based on SNMP

Abstract

Purpose: In an era defined by digital interconnectedness, the stability and performance of computer networks have become paramount for organizations across the globe. The main goal of this paper was to design and implement a network monitoring system for enterprise local area networks based on SNMP. Thus, the focus of this comprehensive study centered at the intersection of cutting-edge network management technologies: Simple Network Management Protocol (SNMP), Paessler Router Traffic Grapher (PRTG) Network Monitor, and Graphical Network Simulator 3 (GNS3). This research project embarked on an exploration of the pivotal role played by SNMP-Based Network Monitoring Systems in ensuring the seamless operation, robust security, and optimized performance of modern networks. So the synergy between SNMP, PRTG Network Monitor, and GNS3 was a central focus of this study.

Materials and Methods: We meticulously configured an integrated testbed combining GNS3, PRTG and SNMP to create a robust network monitoring solution. GNS3 simulates a virtual network environment where SNMP agents on emulated devices collected performance data. PRTG, configured with SNMP sensors, monitors and visualizes the collected metrics. This setup facilitated the testing of network scenarios and the evaluation of monitoring capabilities in a controlled environment, enhancing the understanding of network behaviour and performance.

Findings: Through meticulous investigation, we unraveled the fundamental principles of SNMP, delving into its core components and intricate workings. We demonstrated its versatility as a standardized protocol, capable of managing and monitoring an extensive array of network devices. In doing so, we demonstrated the invaluable role SNMP plays in empowering network administrators to maintain a vigilant watch over their network infrastructure. By harnessing the power of PRTG's real-time monitoring capabilities and GNS3's emulation prowess, we unveiled a dynamic partnership that revolutionized network monitoring and testing. Practical case studies and real-world examples illuminated the profound implications of this integration, demonstrating its potential to optimize network performance, detect security threats, and ensure resource allocation efficiency. In conclusion, it is evident that SNMP-Based Network Monitoring Systems, when harnessed in concert with PRTG , serve as indispensable tools in the arsenal of modern network administrators.

Contributions and Recommendation: In summary, this study underscored the enduring relevance of SNMP-Based Network Monitoring Systems in a digital landscape characterized by perpetual evolution. As networks continue to expand and grow in size and complexity, the triad of SNMP, PRTG, and GNS3 promises to remain at the forefront of innovative and effective network management practices. The insights gained from this research have contributed to the ongoing journey of ensuring the reliability, security, and efficiency of computer networks in an ever-connected world. Recommendations for ongoing training, enhanced security measures as a result of evolving cybersecurity threats, customized alerting, scalability planning, and integration with IT management systems pave the way for future advancements in network management practices.
