What is SD-WAN?
Learn about the capabilities you should expect to find in a full-featured SD-WAN design and how these features operate within the larger Secure SD-WAN architecture.
Futuriom outlines the market trends for SD-WAN in their June 2020 report and provides their predictions for growth and change in the space.

Learn about the Versa Secure SD-WAN solution in a high-level, one minute overview.
Versa Secure SD-WAN is a single software platform that offers multi-layered security and enables multi-cloud connectivity for Enterprises.
A fundamental transformation is occurring with the management and control of applications, as network edges become software-defined, which goes far beyond today’s destination-based routing.
Significant advantages can be achieved using cloud-native SD-WANs to bring greater levels of application intelligence to business connectivity. Application-aware routing understands the paths applications need to take and provides greater management and control to deliver a quality user experience. Rather than focusing on just the network destination, and the complexities of their underpinnings, the emphasis is placed upon the applicationexperience need. Application-aware routing supports the business intent and context of how applications are used and need to be served, based on the business policies the organization prescribes.
SD-WAN uses active and passive monitoring of the fabric to dynamically track path and network characteristics, like packet loss, latency, jitter, load, bandwidth capacity and circuit cost. SD-WAN leverages the information it collects between edge/branch locations, and selectively directs application flows along the most optimal network paths that meets the business intent.
Application-aware routing directs traffic based upon an application’s predetermined SLA and user defined applicationprofiles. Traffic is automatically sent to WAN links that have the required network characteristics and path conditions to support these applications in real-time.
There are multiple advantages from application-aware routing, such as:
Rather than simply directing traffic based on routing protocols, Versa identifies, classifies and secures traffic based on the application ID. We leverage a database of over 3,600 application signatures and 100 million URLs, in concert with application session flow analysis as match conditions, combined with SLA definitions for dynamic routing-oriented steering policies.
Additionally, Versa can set up application-intelligent VPNs and connectivity with minimal configuration. For example, a site-to-site full-mesh VPN topology can be cost-effectively and quickly deployed, to deliver the highest levels of redundancy, which supports latency-sensitive applications like voice and video. Hub-and-spoke VPN topologies can also be set up to support Point-of-Sale (POS) or Electronic-medical-record (EMR) applications for compliance purposes, to ensure those services are routed through asecure hub site.
Versa’s Secure Cloud IP Architecture with application-aware routing, includes:
SD-WAN abstracts application awareness and intelligence from the underlying network infrastructure, enabling enforceable policies to be applied based on application experience to create a businessintelligent WAN. SD-WAN can lower bandwidth costs and reduce network operations costs, while delivering the network agility and reliable connectivity enterprises require. But not all SD-WAN solutions are truly application user-experience aware. To achieve the full benefits that a business intelligent WAN can provide, an application-aware solution that optimizes the user experience is a key ingredient.
