The procedures of implementing a corporate network required the procurement of specialized hardware which is often expensive. However, there is a need to build, design and test networks before the actual deployment to make the entire procedure free from errors. This program allows the network administrator to simulate complex networks without the need to buy dedicated network hardware such as switches and routers. It presents the network admin with a cost-efficient means to test configurations and experiment features which shall be deployed in a production network.
Besides its use by professionals, the application is also useful for students that are studying to take their network exams. Because it simulates an actual network, the student can work with the complex system without the need to have the physical hardware.
You can perform a simulation of networks in real-time (different manufacturer brands), create complex network maps and troubleshooting and proof of concept. You can use the network design as a model for clients before procurement of hardware.
