Traffic Shaping
You can set parameters for the control and shaping of traffic for each policy. The traffic shaping parameters include:
Guaranteed Bandwidth: Guaranteed throughput in kilobits per second (kbps). Traffic below this threshold passes with the highest priority without being subject to any traffic management or shaping mechanism.
Maximum Bandwidth: Secured bandwidth available to the type of connection in kilobits per second (kbps). Traffic beyond this threshold is throttled and dropped.
