As enterprise IT continues its current transformation to rely on the Internet to handle computing tasks, not only software providers must adapt to more cloud uses of their applications, networking equipment makers such as Cisco Systems (NASDAQ:CSCO) also have to address the resulting need for comparable networking hardware. To accommodate the increasingly flexible software deployment and access by enterprises and other communications service providers, networking equipment must now function with scalability in directing and transporting data flows to allow customers making changes to their networking software applications whenever needed. However, this is not how networking equipment is traditionally made and used and has presented a disruptive challenge to the old networking hardware business.For Cisco, its traditional proprietary networking gears of switches, routers, etc. are designed to handle pre-defined network computing tasks with pre-installed, in-house networking software. But one suite of applications doesn't fit all, and customers likely also experience
