How to model and simulate a computer network
OPNET stands for Optimized Network Engineering Tool. It is used to simulate computer networks. The design and configuration of new communication networks is becoming more and more complicated due to the increasing offer of new products to renew and increase networks. Hence for these reasons, it is necessary to use such a simulation tool with the characteristics of opnet. By simulating changes such as technology migration, traffic growth and failures, opnet can help fix existing performance problems before they occur. OPNET provides a virtual network environment where it is possible to analyze and optimize network applications, configurations and traffic flow in nearly limitless range of “what if ” scenarios. Simulation is the process of mimicking or imitating a real world process over time. OPNET is a network simulator which contains a comprehensive development environment supporting the modeling and performance evaluation of communication networks and distributed syst...
