This can help to prevent issues such as dropped calls or poor video quality, which can have a significant impact on business productivity and customer satisfaction.

Tests and Metrics to Evaluate Application Identification Accuracy in SDWAN

Several tests and metrics are used to evaluate application identification accuracy in SDWAN. Tests such as sending different types of traffic to the network and troubleshooting the system’s identification process help to ensure accurate identification. Admins can also use flow-based analysis, which filters traffic based on flow data. Other metrics include packet loss, throughput, and latency, which provide a view of network performance.

One important test to evaluate application identification accuracy in SDWAN is the application signature test. This test involves sending traffic with known application signatures to the network and verifying that the system correctly identifies the applications. Another useful test is the application behavior test, which involves sending traffic with similar behavior patterns to different applications and verifying that the system can differentiate between them.

In addition to tests, admins can also use machine learning algorithms to improve application identification accuracy in SDWAN. These algorithms can analyze network traffic patterns and learn to identify applications based on their unique characteristics.
