MPLS is a reliable and secure technology for building a fixed-path VPN over an IP network between branch offices and headquarters/ data centers. Enterprises commonly choose MPLS network to connect their offices at different locations. However, enterprises with MPLS networks are still facing challenges such as high cost, long lead time for deployment, backhaul penalties, etc. 

Traditional WAN

Issues:
>  Private WAN 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.

>  Depending on a single WAN path or carrier has become a liability that enterprises should avoid when deploying and upgrading their WAN.

>  For the purpose of failover, some enterprises might apply other forms of WAN connections like broadband for backup purposes, which mostly stays idle and literally wastes the bandwidth resources. Besides, a failover also meant all the current sessions would be lost and typically the failover process and time frame was not ideal.

>  As enterprises move towards cloud-based services, traditional WAN based on conventional routers are not addressing the performance need for cloud applications. The reason being is that they typically require backhauling all traffic, including cloud and general web traffic, from branch offices to a central hub. Moreover, some enterprises have the mechanism of advanced security inspection deployed at the central hub. These things aforementioned will delay cloud applications, resulting in a poor user experience and lower productivity.

Solution: Q-Balancer SD-WAN
Software-defined WAN (SD-WAN) technology is the solution to meet the challenges. SD-WAN offers augmented connectivity, better cloud application delivery, simplified WAN operations, and reduced operational costs for those managing public and private WAN connections. Q-Balancer SD-WAN delivers a business-class, secure, simple, and cloud-enabled WAN connection with as much open and software-based technology as possible through augmenting or even replacing traditional MPLS with affordable Internet bandwidth.

Q-Balancer SD-WAN

Building an Intelligent WAN
Q-Balancer branch gateways enable simultaneous use of multiple paths and automatically failover to secondary path(s) in the event of WAN outage or brownout. The branch gateways also have the ability to direct traffic to the optimal path or distribute traffic across the selected paths. The centralized management system makes all branch networks easy to provision, manage, and monitor. Q-Balancer delivers a business-class, secure, and simple cloud-enabled WAN connection with as much open and software-based technology as possible. Also, it provides the visibility for admins to view traffic within the network.

The Components of Q-Balancer SD-WAN
>  Branch Gateway
All Q-Balancer devices support multiple WAN transports across broadband, MPLS, and cellular 4G LTE links. Software features include the ability to route and prioritize traffic being sent to the data center, public cloud infrastructure or the Internet. Each device also supports High Availability (HA) requirements (e.g. active/active and active/standby), making it ideal for sites that need full redundancy. 

>  Headend Gateway
Q-Balancer Headend Gateway deployed in headquarters or data center environments work as VPN concentrators to terminate traffic from branch gateway devices. The headend gateways work together with branch gateway devices to enable seamless failover and secure connectivity. Q-Balancer Headend Gateway can be either physically or virtually deployed in public or private cloud infrastructures.

>  Centralized Management System
QBManager is a centralized management system providing comprehensive and powerful features for enterprise networks such as automatic provisioning, configuration management, and monitoring.
