Network designers are constantly challenged by the growing complexity of communications protocols and the increasing scale of network deployments. Network R&D is no longer a process that can be conceded to spreadsheets or traditional software. In order for Network R&D organizations to innovate, they need robust network simulation software to easily and intuitively model the intricate end-to-end behavior of protocols. The solution must also be able to efficiently analyze the performance of these protocols and technologies in network infrastructure models of realistic scale.

OPNET’s Network R&D solutions are the industry's leading software for network modeling and simulation. They are used by the world's premier network engineers to design communication networks, products, technologies, and protocols with unmatched flexibility and scalability.
