As part of its commissioned "Post-5G Information and Communication Systems Infrastructure Enhancement R&D Project" (hereinafter "the Project"), NEDO has been working to establish foundational technologies for automated network operation. In line with this, Alaxala Networks Corporation (hereinafter "Alaxala") and Keio University have successfully developed a high-precision "silent failure detection technology" that detects minute packet loss of less than 1%—a level previously difficult to detect—while simultaneously reducing both missed detections of anomalies and false positives.
In addition to this technology, they have developed a "flexible network sensor technology" that identifies and controls flows from hundreds of millions of devices and performs traffic information collection and bandwidth control with flexibility, efficiency, and high precision, as well as a "resource control technology" that performs optimal data collection and bandwidth control as needed without burdening the network. Furthermore, by combining these technologies, they have developed a "dynamic drill-down control technology" that performs high-precision anomaly detection and analysis with a small amount of collected data and computational resources. This has led to the development of an advanced network monitoring and control technology (hereinafter "this technology") that enables networks to autonomously and precisely perform anomaly detection and analysis.
By improving the detection accuracy of communication quality degradation and service failures, including silent failures, and by realizing advanced monitoring operations to support the increasingly connected and diverse services of the post-5G era, this technology will contribute to simplifying network operation, addressing the shortage of human resources, and advancing the development of networks in the post-5G era.
