1) The document discusses the challenges that new technologies like mobility, cloud computing, big data, social networks and the Internet of Things pose to current rigid networks. 2) It proposes that networks need to become more agile by shifting their focus from individual technologies and devices to prioritizing user experience, implementing dynamic auto-deployment, and moving from single-point to complete network management. 3) Key innovations from Huawei that help enable agile networks include their Agile Campus solution which uses SDN architecture for zero-configuration switching and APs, quality monitoring technologies for IP networks, and converged wired and wireless solutions.
