IDC researchers who were panelists at the Interop conference said there are network limitations from increasing mobility and virtualized environments, which will drive the development of new scalable networks. "Cloud and mobility are the two key paradigm shifts when it comes to enterprise IT networks," said IDC's Rohit Mehra. "[The network] was static and reliable, and it met the needs of IT. That needs to change now. Why does it need to change? Because of the explosion of traffic."
