What is network modeling?

Are your network designers 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.
