5G SA HTTP2/GTP-U Extraction and Correlation

This feature enables deep packet analysis and session-level correlation for 5G Standalone (SA) user plane traffic. It extracts key information from GTP-U tunnels and correlating it with HTTP/2.

Key Functionalities:

• GTP-U Extraction:

  • Decodes GTP-U headers and retrieves inner IP payloads for user-plane sessions.

  • Extracts key identifiers such as TEID, UE IP, QoS Flow Identifier (QFI), and Tunnel Endpoints.

• HTTP/2 Extraction:

  • Parses HTTP/2 requests, responses, and headers (e.g., :method, :path, :authority).

  • Identifies and reconstructs HTTP/2 streams over TCP/QUIC sessions.

• Correlation Engine:

  • Maps GTP-U session data with corresponding HTTP/2 flows using UE IP and session metadata.

  • Enables per-user, per-session correlation between transport and application KPIs.

  • Provides detailed insight into end-to-end user experience metrics.

• Analytics and Export:

  • Generates per-session KPIs (latency, throughput, error rate, retransmissions).

  • Supports export to Kafka, ElasticSearch, or external monitoring systems.

Benefits:

• Enables end-to-end visibility from 5G transport to application layer.

• Improves troubleshooting of latency, congestion, and QoS degradation issues.

• Enhances KPI accuracy by linking transport sessions to application activity.

• Provides valuable data for network optimization and service assurance.
