Software Defined Wide Area Networks (SD-WAN)

Boost network data rates, reliability, and flexibility while slashing connectivity costs.

What is SD-WAN?

Software-Defined Wide Area Networking (SD-WAN) is a revolutionary way to approach the simplification of branch office networking and assure optimal application performance by using centrally controlled and managed WAN virtualization. Unlike traditional WANs, SD-WAN delivers increased network agility and cost reduction. The geek speak summary is – the principle of SD-WAN is to abstract the network hardware and transport characteristics from the applications that use the network.

In the early development stages of our hosted voice solution, we determined that WAN optimization was needed so we made it so. As pioneers in deploying SD-WAN (remember SDN and ATM?), Swordfish worked to craft a solution together that provides elevated quality of service on your existing network connection(s). This ensures your critical voice communication service has the bandwidth it needs without compromising call continuity and call quality.

SD-WAN is WAN Virtualization

In the same way server virtualization abstracts the underlying physical hardware from the logical virtual servers that run on it, WAN virtualization is where a logical WAN connection (to either the Internet or between branch offices) can use multiple underlying connectivity technologies (like xDSL, Cable, MPLS, cellular and fiber) at the same time but presents this connectivity to users and applications as a single direct to Internet or secure site to site connection.

SD-WAN is Intelligent

SD-WAN enabled networks are capable of monitoring WAN health and quality, then using these measurements to make intelligent decisions on application traffic flow. This arrangement has several key benefits:

  • Real time services like VoIP and video can be sent via the lowest latency link.
  • Intelligent failover and active/active configurations can be used to guarantee reliability even when a WAN link fails.
  • WAN connectivity can be added as and when required to provide agility.

Best of all, once configured, all traffic is managed automatically by the software defined rules set on the device – no human interaction is required.

SD-WAN is Centrally Managed and Monitored

Branch offices can be provisioned, monitored and managed centrally using a SD-WAN controller that gives network administrators full control over their wide area networks and remote devices using a single interface.

Complex VPN configurations connecting thousands of branch offices together securely (using whatever connectivity is available at each location) can be created and deployed automatically, with centralized WAN monitoring and notifications providing a real time view of WAN health and globally branch office availability.

The Swordfish SD-WAN Advantage

Over the years, we have developed a potent combination of products and technologies that can help you build SD-WAN networks with unbreakable connection resilience, unmatched deployment flexibility, intuitive ease of use and the lowest total cost of ownership.

Add Bandwidth Anytime.

Need more bandwidth? Just add more links from any ISP. Swordfish’s routers seamlessly integrate them into a multi-WAN connection pool accessible to all network clients, no matter where they’re located. Wireless SD-WAN Load Balancing is rapidly deployable, making it ideal for worksites, transportation, maritime deployments and more.

100% Uptime with Hot Failover.

Hot Failover keeps your network up and running by routing traffic around inactive or intermittent connections. You can even use our cloud-based SD-WAN controller to define Hot Failover’s behavior, specifying conditional or dedicated backup links that dynamically respond to network status.

Prioritize and Balance Traffic.

Swordfish SD-WAN incorporates 8 application-aware link load-balancing algorithms and customizable rules that put you in complete control of network data priorities. Simply set your traffic priorities, including VoIP and custom application traffic, and let Swordfish take care of the load-balancing and optimization details.

Accelerate Visitor Access.

Inbound Load Balancing Algorithms enable visitors to enter your server through different Internet links to enhance the customers experience with faster response times and higher speeds. Hosting Email, e-commerce, VoIP, and other business applications has never been easier, faster, and more reliable.

Simple. Powerful. Productive.

When our old phone system started to die on us, we needed an entire technology refresh fast! Swordfish replaced the equipment in a very short time frame while keeping us in business. That’s what I call disaster avoidance. They are the best!
