ZK Research: Cisco’s Branch Infrastructure Powers the Hybrid WAN

IT has gone through a significant evolution over the past decade. Virtualization has changed the entire face of the data center, the network edge has become predominantly wireless and consumer devices reign supreme. However, one of the few areas of IT that has yet to evolve is the corporate wide area network (WAN). Managing the WAN is something network managers have always struggled with because WAN speeds are typically an order of magnitude, or more, slower than local area networks (LANs).

Historically, while not ideal, WANs met the needs of the enterprise as many mission-critical applications were deployed locally, and WAN-based applications were best effort in nature. Today, the model has changed. Companies are adopting network-centric compute models such as cloud (Exhibit 1), mobile computing and the Internet of Things (IoT), which raises the value and importance of the corporate WAN. In addition, the significant rise in video, VoIP and virtual desktop traffic drives the need to evolve.

As application performance becomes more dependent on the network, application delivery requires IT to be more network centric. For this to happen, the network must shift from a tactical resource to a strategic asset that will play a key role in IT success. However, for the WAN to achieve this level of strategic importance, it must evolve into a hybrid WAN.
