Cross-Subnetwork Packet Trace Data Retrieval

The patent merges the data collection process across multiple subnetworks by having each subnetwork's entity store and contribute its received packet data to a unified trace. Instead of manually collecting data from each subnetwork separately, the system combines data from all subnetworks through automated requests and responses, eliminating the need for multi-service team coordination and significantly reducing collection time while maintaining completeness.

The patent implements self-service anomaly detection by enabling automated request-response mechanisms where entities in subnetworks can independently query and obtain packet trace data without requiring manual crisis management bridges. The system automatically identifies and retrieves relevant data from appropriate subnetworks, reducing the complexity of crisis management structures while maintaining reliable anomaly detection capability.

The patent implements a universal request-response mechanism that works across all subnetworks regardless of their administrative compartmentalization. Each subnetwork entity can receive and process standardized requests for packet trace data and provide responses in a unified format. This multi-functional approach allows independent subnetwork management to be maintained while enabling seamless cross-subnetwork data retrieval without coordination overhead.

The patent addresses clock offset issues by modifying the time reference parameter when correlating packet data across subnetworks. Instead of requiring all subnetworks to use a single unified time reference (which would reduce flexibility), the system dynamically adjusts time parameters based on the specific subnetwork's clock offset, maintaining both measurement precision and time reference flexibility.
