The document discusses how networks must change to adapt to shifting traffic patterns, limited visibility and control, and network latency. It notes that by 2015, 50% of CIOs expect to operate in the cloud. The network evolution involves moving to a model with direct internet access from branches for lower latency and cost, using technologies like WAAS, PfR, AVC and MPLS to provide transport independence, intelligent path control and secure connectivity. This integrated approach aims to optimize applications across multiple access types including wireless. The network must also adapt to growing numbers of devices and traffic speeds increasing from Mbps to Gbps and beyond. Cisco provides a range of solutions from routers and switches to wireless controllers and management platforms to allow for a unified
