Software-defined wide-area network, commonly referred to as SD-WAN, is an evolution of wide area networking concepts that have been in use in enterprise for the past two decades. It is important to consider not only core features provided by SD-WAN, but emerging features and legacy integrations when identifying the SD-WAN solution right for your organization.
Organizations mainly used leased lines from service providers to interconnect traditional WAN locations to central data center hubs. Traffic flowed from a remote spoke to a central hub to reach applications, services and public internet available in the central locations.
The hub-and-spoke design concept was a suitable model for years as organizations became more interconnected, thanks to the ability to centralize services in a few core locations.
Over the past few years, applications started to become widely available outside of the centralized hubs due to proliferation of cloud-based applications provided as a service that could be consumed using standard Internet access. Traditional WAN architectures became a performance bottleneck for the new application models.
SD-WAN technology was born to solve these new challenges. The first generation of SD-WAN solutions provided a new foundation of features for WAN architecture improvements.
The foundational features of SD-WAN offerings include transport independence, application visibility, path intelligence and centralized management.
The concept of transport independence is not new; network engineers have been encapsulating traffic for years. SD-WAN expanded on this concept by making the IPSec protocol a core component of the architecture. This provided the ability to create a virtual network, or overlay, on top of any service provider or connection and generate greater flexibility in introducing commodity connectivity, such as broadband access, into remote locations.
Application visibility and path intelligence are also possible due to overlay technology, as well as the fact that load balancing across connections has become standard. Users of an SD-WAN solution have the ability to build policies based on an application type and performance requirements, and path monitoring allows for business-critical applications to be routed across any available connection that meets policy definition.
Finally, SD-WAN provides centralized management. Gone are the days of configuring hundreds of routers using a CLI interface.
Central management allows for common templates to be developed based on site type reducing the variations of configurations that were deployed in the WAN. The central management tools also have Application Programming Interfaces (APIs) that allow for customizable automation that can be accessed using HTTP-based RESTful interactions.
More recent additions to the SD-WAN feature portfolio include integrated security and optimizations for integration with cloud connectivity. Furthermore, SD-WAN comparisons have expanded to include legacy integrations, ensuring a smooth transition without disruption to the operations of the organization.
