OPNET is a simulation software tool with rich and complex set of libraries to model, configure and simulate the entire heterogeneous network. Computer network of the Campus consists of access points, switches, routers, servers etc. The model on OPNET is configured and simulated to analyze traffic load, delay, data rate, LAN and WLAN characteristics, ping reports and network efficiency. The project results in best settings for our network and can predict the cost, traffic behaviors, throughput and efficiency of the network beforehand. I will be using the OPNET (Optimized Network Engineering Tools) to find a delay, load and throughput of network by applying different network conditions. After analyzing the results through graphs I will choose the best setting for network.
