SD-WAN

Introducing SD-WAN
SD-WAN (software-defined WAN) is a specific application of software-defined networking (SDN) technology applied to WAN connections, which are used to connect enterprise networks, including distributed networks. It is a revolutionary approach to simplify branch networking and assure enterprise application performance to the cloud.

In the past, a WAN might be used, for example, to connect branch offices to a central corporate network, or to connect data centers separated by distance. And these WAN connections often used technology which required special proprietary hardware. However, enterprises today are demanding more flexible, open, and cloud-based WAN technologies, rather than installing proprietary or specialized WAN technology that often involves expensive, fixed circuits, or proprietary hardware.

The main goal of SD-WAN technology is to deliver a business-class, secure, and simple cloud-enabled WAN connection with as much open and software-based technology as possible. Our SD-WAN solution creates a smart and responsive network, one that adapts in real time to bandwidth demand and actual network conditions, ensuring that presently and regardless of network issues, critical applications have priority and all applications take the best quality path through the network, ensuring uptime so business can get done. Q-Balancer SD-WAN solution has three main components. Each of these components have a very specific role as described below:

  • Controller – centrally manages and distributes services and application policies
  • Edge – are the hardware or virtual routers at the branches delivering cost-effective services, and addressing application needs
  • XBond –  is an overlay network that securely links all edge appliances and controller

Whether the WAN is all MPLS, a hybrid WAN of MPLS and broadband, all Internet links, backed up with wireless, or extended to the cloud, Q-Balancer SD-WAN solution ensures continuous availability and predictable application performance to keep productivity moving at optimal speed.

Increased Flexibility
SD-WAN enables enterprise networks to manage multiple types of Internet connections, from MPLS to broadband to LTE. Complex distributed network configurations connecting thousands of branch offices together can be deployed instantly whether broadband is available at each location. With SD-WAN technology branch offices can be provisioned, managed, and monitored centrally, which gives network administrators increased flexibility to control over their WAN and remote devices using a single interface.

Better Application Performance
SD-WAN technology aggregates at least two links together to create a single bonded link, which is faster than either one individually. Q-Balancer SD-WAN provides remote/branch offices with enough bandwidth by bonding all available WAN links to compose overall bandwidth, which is appropriate for single applications.

Reduced Complexity
Routing protocols don't react to changing network circumstances such as packet loss, excessive jitter, or congested links; routing protocol metrics simply don't include that sort of information in their best path calculations. Measurement techniques like IP SLA can artificially change metrics or otherwise override the normal behavior of a routing protocol, but these are tricky tools to configure. SD-WAN technology handles those inconvenient tasks for an enterprise in an automated way, routing and rerouting traffic dynamically based on the real time state of the network. The complexity will be reduced as SD-WAN takes care most of it. With SD-WAN technology, an enterprise should be able to rely more on broadband and less on leased-line.

Lower Cost
In enterprise networks with traditional WANs, some costly technologies, such as leased line, are integrated to deliver the end-to-end connection. SD-WAN takes active measurements between endpoints to learn whether the broadband link is capable of carrying, say, voice or video traffic reliably. As a result, enterprises should be able to invest more in low-cost broadband links and so as to minimize the size of their expensive private links.

Limitless Business Opportunity
Wherever your business goes we are right there for you. As long as your business has a demand for undisrupted network continuity, we will be there for you. Q-Balancer SD-WAN can be deployed in across various networks, from company networks, site-to-site, to M2M.
