The key to providing the quality of service needed to support delay sensitive applications such as voice and video is maintaining tight control over network utilization, error rates and packet discards. Traffic Sentinel's thresholding engine rapidly identifies problems that might impact quality of service.
The red box in the row labeled Embarcadero indicates that a utilization threshold has been exceeded in this zone (we have already detected a significant increase in packet jitter in this zone). Drilling down on this status box provides details about the location of the congestion.
