Comparative Analysis Performance of Dynamic Routing OSPF and Segment Routing

In modern network, Routing protocols face issues that must be addressed to ensure optimal performance. Routing involves sending data packets from one device to another through a network. Key issues include network complexity and performance. Dynamic routing, using the OSPF protocol, automatically selects the best path in the network. However, OSPF's link-state database grows with the network, requiring more memory and processing power. Dynamic routing performance can degrade due to changes in topology and disruptions, affecting user experience and operational efficiency. As network complexity increases, Segment routing is becoming more popular. It allows users to specify paths for specific service requirements, improving overall performance. Segment routing offers control flexibility and scalability, enabling easier management of data paths. In this Paper, the comparison between Dynamic routing OSPF and Segment Routing method will be measured. The parameters used for testing are Routing Performance metrics and Quality of Service (QOS). The measurement results show that segment routing provides higher throughput, and lower packet loss compared to dynamic routing OSPF. In addition, segment routing also shows better jitter performance, making it a more effective solution for high-complexity networks. Specifically, Segment Routing achieved a convergence time of 0.047 s in Topology A and 0.046 s in Topology B, outperforming Dynamic Routing OSPF, which had convergence times of 0.052 s and 0.048 s, respectively.
