Protocol inspection utility for visualizing GTP-C (v1/v2) and GTP-U packet structures, Information Elements, and multi-hop bearer paths across LTE and 5G NR interfaces.
GTP handshake visualizers show GTPv1/v2 control-plane sequences so EPC troubleshooting starts from the correct expected message order.
The visualizer parses GTP message type codes and IE definitions from 3GPP TS 29.274 (GTPv2-C) and TS 29.281 (GTP-U), rendering a structured view of each field with compliance notes.
Built on 3GPP Technical Specifications, ensuring accuracy for production deployments and security audits.
Calculations specifically designed to identify protocol vulnerabilities and signaling misconfigurations.
GTP is a frequent target of mobile network attacks (GPRS Tunneling Protocol vulnerability). This tool aids security researchers and network engineers in understanding GTP flows for defensive analysis.

If a trace stops after Create Session Request with no response, the visualizer points you at SGW/PGW path and cause-code investigation rather than RAN.
Simplified for learning; vendor proprietary IEs may appear in real networks.
Common GTPv1/v2 control-plane flows such as create session / create PDP context style handshakes used in EPC and related evolutions.
No. It teaches expected order and actors so you can read pcaps faster.
Message names and IEs differ. Mixing them in troubleshooting causes false conclusions about “missing” messages.
IPv4 CIDR boundary and host range calculation tool.
Estimate the cryptographic resistance and brute-force complexity of mobile encryption algorithms.
Calculate the composition and signaling footprint of 3GPP authentication vectors across generations.
