Software-defined wide area networking (SD-WAN) is making organizations rethink their WAN infrastructure. Instead of connecting a location with one highly-available MPLS connection, SD-WAN can connect a location with multiple, less-reliable broadband Internet connections, selecting the optimum connection per application.

In 2019, it became clear that SD-WAN had secured its position as the way forward for enterprise WAN connectivity. Market adoption is growing rapidly, and industry experts have declared a winner in the SD-WAN vs MPLS debate. SO WHAT IS SD-WAN? Whats driving all the excitement around SD-WAN?

Enterprise networking is moving from traditional hub-and-spoke WAN architectures to infrastructure that must support the migration of critical applications to the cloud. MPLS: Reliable, But Comes with a Price The popularity of MPLS deployments in corporate WAN infrastructures comes from its predictability.

What is the ROI on SD-WAN projects? Most enterprises look at SD-WAN as an MPLS alternative , hoping to reduc e their MPLS connectivity costs. But the actual SD-WAN ROI is a mix of hard and soft savi n gs from increasing overall network capacity and availability to a reduc ed operational load of managing and securing the network.

It had risen as a response to the business need for a reliable and predictable network performance across the wide area network (WAN). Unmanaged Internet-based global routing, which I will refer to as the middle mile, is a convoluted mess of communication service providers, links and routers. Enter the Hybrid WAN.

The answer Software-Defined Wide Area Networks (SD-WANs). SD-WAN brings unparalleled agility and cost savings to networking. With SD-WAN, organizations can deliver more responsive, more predictable applications at lower cost in less time than the managed MPLS services traditionally used by the enterprise. How Does SD-WAN Work?

Software-defined WAN (SD-WAN) provides the ability to implement a secure, high-performance corporate WAN on top of existing networks. However, SD-WAN infrastructures must be carefully designed and implemented to provide full value to the organization. SD-WAN is also beneficial for remote workers.

Changes in our applications (cloud migration) and where users work (mobility) are driving the shift to software defined wide area networks ( SD-WANs ), but theyre also forcing us to rethink how we securely connect our users, application and data and deliver a compelling quality of experience. Mobile users are not supported at all by SD-WANs.

MPLS (Multiprotocol Label Switching) is a network routing technique that is based on predetermined paths, instead of routers determining the next hop in real-time. This enables quicker and more efficient routing, as the router only needs to view a packet label, instead of looking up the address destination in complex routing tables.

Rather than collecting only flow data from routers, or only eBPF information from containers, the fact that application traffic traverses so many devices means we need much more data to get an accurate view of what’s happening.
