Q-Balancer 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 Q-Balancer 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 four main components, each of which has a very specific role as described below:

> Q-Balancer Network Controller – centrally manages and distributes services and application policies.

> Q-Balancer Edge Appliances – are the hardware or virtual routers at the branches delivering cost-effective services, and addressing application needs.

> Q-Balancer XBond – is an overlay tunneling technology that securely links all branches and HQ/ Data Center.

> Q-Balancer Reporting – provides visibility into real-time and historical view for troubleshooting, and capacity planning.

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

As illustrated in the diagram above, Q-Balancer appliances are respectively deployed at both HQ and branch office. The public WANs (red and green) in this case are transport agnostic, while the private backhaul is with MPLS line (blue). Cloud-based applications from branch office will be directed to the cloud via public WANs(red and green) without going through the private WAN (blue). The delivery for the applications hosted at data center is improved as the backhaul bandwidth is reserved for them, while Internet-bound communications is offloaded from the private backhaul.

Increased flexibility

Q-Balancer SD-WAN enables multiple locations within an enterprise to be inter-connected with transport-agnostic services. 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. Q-Balancer SD-WAN enables distributed enterprises to benefit from: 

Better application performance 

Q-Balancer 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 application. 

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. Q-Balancer 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 the SD-WAN takes care most of it. With Q-Balancer SD-WAN, an enterprise should be able to rely more on broadband technology and less on MPLS/ 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. Q-Balancer 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 the business goes we are right there for you. Q-Balancer SD-WAN can be deployed in across various networks, from corporate network, branches, and vehicles.

Q-Balancer is also incorporated with WAN failover, WAN restoration, WAN load balancing, VPN bonding, and many enterprise-grade features such as Firewall, DHCP, routing protocols of OSPF & RIP, and end-to-end WAN QoS, all of which help enterprises take full advantage of hybrid WAN networks at corporate networks, data centers, branch offices, pop-up stores and sites, and vehicle network.
