What is Hybrid Wide-area Network (WAN) and How Does It Work!

Hybrid SD-WAN is one of the most popular use cases that enterprises are looking for solutions today! With the implementation of SD-WAN solutions, service providers have an opportunity to use a hybrid to increase business possibilities.

What is Hybrid WAN?

Hybrid WAN is a method of correlating two geographically separated WANs to a branch office with the traffic being sent over two separate connections.

  1. Traditional MPLS
  2. Broadband connection

Where all the regular business or enterprise traffic that is expected to go to the data center takes the MPLS route, and the quicker data such as credit card payments, etc take the faster broadband route.

How Does a Hybrid WAN Work?

There is a reason why enterprises focus on hybrid WAN, this trend in wide area network matters because it finds solutions to predicaments that occur with the more traditional WAN architecture. By channeling traffic undeviatingly to the Internet, it reduces excess bounces and latency that can frequently happen when traffic goes through a data center. 

A hybrid WAN has increased cost-efficiency because regulating traffic over the Internet is by far less costlier than using an MPLS link.

Hybrid WANs have been around for almost a decade in various forms, often in separate networks such as the internet, MPLS and LTE; which are connected by different service providers to different sites. These solutions are not always the most practical for various enterprises because it is difficult for them to manage all the service providers simultaneously. For service providers, also there are some serious challenges with the Hybrid WANs, such as:

  • MPLS lacks agility and is complex: The issue with MPLS is that it takes anywhere between 3 to 4 months to provision MPLS services. it’s also not always practical to connect sites that are small and may not have better accessibility
  • Affordability and cost: For those smaller sites sometimes internet connections are not always available, therefore that can be an issue to have an MPLS, an idle LTE or internet connection; and also most smaller companies cannot afford multiple connections
  • Inability to connect 2 or more connections: When a site has multiple connections it cannot use the fusion of using all of those combinations simultaneously.
