Increasing Backhaul Capacity

Q-Balancer increases network backhaul capacity by aggregating multiple site-to-site WAN connections. This increases bandwidth capacity and accelerates application transmission over enterprise backhaul between locations.

Broadband WAN Bonding

Q-Balancer XBond is an overlay network that securely links all edge appliances and controller. Q-Balancer site-to-site WAN bonding consists of XBond and tunnel bonding. Through our application centric overlay bonding tunnels, enterprise is able to virtually combine multiple 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 by using the packet-level WAN bonding to aggregate the bandwidth.

As the backhaul performance and availability can be increased, businesses enjoy highly scalable and leased line-like backhaul at a fraction of the cost of traditional business leased lines.


Cellular WAN Bonding

For the remote offices where landline might not be available or can not be ready in time, Q-Balancer Cellular WAN Bonding offers enterprises an undisturbed network backhaul with its ability to harness multiple 4G LTE connections. The technology also enables these remote networks to flexibly employ a combination of wired and wireless broadband technologies. This provides multi-office enterprises a highly resilient and scalable network with a very little lead time.

As illustrated in the diagram above, a Q-Balancer Mesh at branch network is connected with three 4G LTE lines, while the other Q-Balancer is sitting at HQ/ data center working as a network controller. The Q-Balancer appliances at both ends work together to aggregate the bandwidth of 4G LTE lines, which augments the performance and reliability for the network backhaul. Should one the 4G LTE line fails, the backhaul traffic will be seamlessly diverted to the remaining active path(s). This improves reliability for the enterprise backhaul. All 4G LTE lines are set active, and so the branch network is able to access headquarters at a fully aggregated speed at all times.
