A Review of Network Scalability Testing Using Simulation

Network scalability is a fundamental requirement for modern distributed systems, including cloud computing, Internet of Things (IoT), and next-generation wireless networks. This paper presents a comprehensive review and experimental analysis of network scalability testing using simulation techniques. Simulation-based approaches enable cost-effective and flexible evaluation of network performance under varying loads. In this study, a discrete event simulation model is implemented to analyze throughput, delay, and packet loss across increasing network sizes. The results demonstrate that as network size increases, system performance degrades due to congestion and resource limitations. The paper also compares widely used simulation tools and highlights key challenges and future research directions in scalable network design.
