QoS is the ability to prioritize network traffic to ensure that adequate bandwidth is always available to specific bandwidth-intensive applications, especially during periods of congestion. QoS rules determine bandwidth minimums and maximums for specific types of traffic and use load balancing and automatic failover to direct this traffic to links with sufficient bandwidth.

Based on user-defined QoS policies, PowerLink™ controls the link bandwidth allocations to support applications that are prioritized, and which ISP links they are going over.
