Increasing Backhaul Capacity for Critical Applications

The capacity of enterprise backhaul networks is in higher demand as data requirements increase due to rising use of videos, guest networks, IoT data, and latency-sensitive applications such as voice. Backhauling Internet-bound traffic consumes expensive bandwidth, and adds latency which negatively impacts performance for critical applications. The Q-Balancer SD-WAN solution enables businesses to increase backhaul capacity by combining bandwidth of wired or wireless broadband WANs.

>  Increasing Backhaul Capacity
Q-Balancer increases enterprise network backhaul capacity with the ability of aggregating multiple site-to-site WAN connections. This increases bandwidth capacity and accelerates application transmission over enterprise backhaul by using the packet-level WAN bonding.

Our Q-Balancer XBond is an inbuilt bandwidth bonding technology that securely links all branch and corporate networks with overlay tunnels, automatically builds policy rules, and aggregates bandwidth of all WAN connections. Through the technology, multi-office enterprise is able to combine its site-to-site circuits and make the bonded circuits work like a virtual leased line. The increased bandwidth theoretically equals to the sum of the separate connections. For example, 3 * 1 Mbps WAN links would provide 3 Mbps of bandwidth.

As the backhaul performance and availability increases through the bandwidth bonding technology, multi-office enterprises enjoy leased line-like and highly-scalable backhaul at a fraction of the cost of traditional business leased lines.

emote offices may find MPLS service is not always available, or takes long time for installation or cost-prohibitive. With many major enterprises operating numerous branch locations across the globe and expanding into new territories, those limits are unacceptable and should be overcome in today’s business world.

The Q-Balancer XBond technology offers enterprises an undisrupted network backhaul with its ability to harness multiple 4G LTE connections. The technology also enables the remote networks to flexibly employ a combination of wired and wireless broadband WAN technologies. This provides multi-office enterprises a highly resilient and scalable network backhaul with a very little lead time.

As illustrated in the diagram above, a Q-Balancer Mesh appliance at branch network is connected with multiple 4G LTE connections, while the other Q-Balancer appliance is sitting at HQ/ data center. The appliances at both ends work together to aggregate bandwidth of the available 4G LTE connections, which increases the capacity and reliability of the enterprise backhaul. Should one the WAN links fails, the backhaul traffic will be seamlessly diverted to the remaining active path(s). As all 4G LTE connections are set active, the branch networks can enjoy a fully aggregated WAN speed at all times.

Traditionally, the router-centric model employed at branch offices backhauls all Internet-bound traffic to headquarters-based security infrastructure to protect the branch from vulnerabilities, and yet this consumes expensive backhaul bandwidth and adds latency which negatively impacts performance of critical-application.

By introducing other types of WAN transport into MPLS WAN, the Q-Balancer SD-WAN can help enterprises reserve MPLS backhaul bandwidth for critical applications by offloading Internet-bound traffic from the backhaul. The solution eliminates the potential for bandwidth waste for backhaul and performance bottlenecks for trusted SaaS and web-bound traffic. For branch networks that are required to backhaul specific web-bound applications for additional security monitoring in accordance with security policy, the Q-Balancer appliance is able to help business optimally direct traffic to the best-performance path based on business intent policy.
