Software-Defined Wide Area Networking (SD-WAN) is a transformative technology that simplifies the IT infrastructure
Software-Defined Wide Area Networking (SD-WAN) is a transformative technology that simplifies the IT infrastructure control and management by delivering a virtual WAN architecture that securely connects users to their applications.The hallmarks of SD-WAN are simplified branch office connectivity, increased reliability, optimized application performance, and increased network agility. SD-WAN lowers total costs, by providing more resource usage and a more automated branch and WAN architecture that is required to fulfill modern IT business initiatives.
SD-WAN aggregates diverse network circuits, like broadband, DIA, and LTE. These circuits can be added to existing MPLS to create a hybrid network, or they can be an alternative to MPLS using all-Internet wired and wireless connections.
How Does SD-WAN Work?
SD-WAN creates an overlay to virtualize the WAN with centralized control to simplify the management and deployment of branch-office services.
Overlay Network
SD-WAN creates a WAN transport agnostic overlay network and can replace legacy branch office routers simplifying the WAN infrastructure. SD-WAN provides greater control and management, providing application-layer control of application service policies, to ensure optimum application performance.

Application Awareness
A key element of SD-WAN is application-awareness. SD-WAN understands individual applications and their SLA requirements and translates them into policies that the network must adhere to. This provides active network and application experience monitoring that ensures optimal traffic delivery and QoE – whether on-premises, private/public cloud, or SaaS.Policy-based Framework
SD-WAN also provides an automated policy-based framework that is propagated from unified control and management, all from a single-pane-of-glass interface. Visibility is enhanced, allowing better IT insights into applications, devices, users, and networking, to ensure adherence to their business goals and objectives. This simplifies ITs ability to define, control, and change business requirements across their branches, data centers, and cloud/SaaS.
