Campus Network Upgrade and Optimization Based on OPNET

By using OPNET simulation platform, the network simulation model of campus network was constructed and the user’s behaviors of the networks were analyzed. The network latency, the page response time and the throughput capacity of the switch were simulated in the original campus network and the extended network. By using the two sets of data for comparison and analysis, the impact of the campus network performance factors and "bottleneck" were found. An appropriate optimization design of the campus network was proposed and simulated again. Through the simulation, the reliability and accuracy of the design will be proved, and the network construction period will be shortened.
