The digital transformation has driven distributed enterprises to adopt cloud data centers and SaaS (Software as a Service) to improve serviceability, and thus SD-WAN has become the ultimate solution to optimize branch office connectivity as more and more cloud applications are used.

The SD-Branch is considered as the evolution of SD-WAN. Since branches are located all over the globe, traditional WAN architecture is inadequate to support the growing use of cloud-based applications. Thus, the concept of SD-Branch has been introduced to address the obstacle. The SD-Branch leverages SD-WAN technology and consolidates multiple networking functions into a single software-defined vCPE platform. All the functions related to branch connectivity and network security are virtualized and centralized. This innovative architecture enables distributed enterprises a simplified and consolidated branch network with enhanced service agility, security and QoS (Quality of Service).
