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. This approach can help to improve accuracy over time and reduce the need for manual intervention.

Common Challenges Faced in Achieving Accurate Application Identification in SDWAN

Faced with an increasingly demanding business environment and mounting cybersecurity threats, achieving accurate application identification in SDWAN can pose significant challenges for network administrators. One of the biggest challenges is dealing with encrypted traffic, which hides application identification information from network administrators. Another is the variety of applications being used on the network which may be new or custom-built, thus challenging traditional identification methods.

Additionally, network administrators may face challenges in accurately identifying applications that use non-standard ports or protocols. These applications may not be recognized by traditional identification methods, leading to misclassification or even complete failure to identify the application. Furthermore, the dynamic nature of modern networks, with applications constantly being added or removed, can make it difficult to maintain accurate identification over time. Network administrators must stay vigilant and adapt their identification methods to keep up with these changes.

How to Enhance Application Visibility Without Compromising on Accuracy in SDWAN

The way to enhance SDWAN application visibility is to use advanced technologies such as machine learning and artificial intelligence (AI) to provide real-time traffic analysis. These solutions use AI and machine learning algorithms to analyze traffic patterns, learn by observing network behavior, and provide recommended actions based on network performance and security issues.

Suppose network administrators combine application visibility with accurate application identification. In that case, they can gain full control over their network traffic while maintaining the best network performance for various applications.
