Steering and Distributing Application Traffic across Available Hybrid Paths

>  Dynamic Path Selection
A branch network in a distributed enterprise often will have MPLS as a primary WAN link and sometimes an idle Internet link(s) as backup. The Q-Balancer Dynamic Path Selection (DPS) has the ability to automatically and selectively route traffic onto one WAN link or the other depending on network conditions or traffic characteristics. The Q-Balancer DPS may steer packets onto a particular WAN because the other WAN is down or not working very well, or distribute traffic across all available WANs. The Q-Balancer DPS enables organizations to fully-utilize all deployed bandwidth at each location. The Q-Balancer DPS eliminates the active/standby configuration as the deployment wastes a great deal of bandwidth. By intelligently distributing traffic across the available WANs, The Q-Balancer DPS turns the standby line into active one without the complexity of pure layer-three routing, and improves the reliability and performance for branch office applications.

As a core component of SD-WAN, the Q-Balancer DPS works in conjunction with path-monitoring and allows network administrators to configure performance criteria for different types of traffic. Given the real-time measuring result such as the level of latency, packet loss and other metrics from path-monitoring, the Q-Balancer DPS allow packets to be directed to an optimal route or distributed across multiple paths. Based on which of the available paths meet these criterias, path selections are then made on a per-flow or per-packet basis. By using a combination of broadband technologies and MPLS in a software-defined WAN (SD-WAN) implementation, enterprise WAN backhaul will be offloaded as the Q-Balancer DPS dynamically routes cloud applications directly out to the Internet cloud from a site based on the metrics.

The Q-Balancer DPS also provides granular control and distribution for application flows across different paths. For example, you can create policies that would route business-critical traffic, e.g. VoIP, through the MPLS network, while the rest of the traffic is load-balanced across all available WANs. Besides, you could also set policies to route the VoIP traffic over uplinks that come with the least packet loss, while the other types of traffic can be sent over the highest-capacity circuits.
