Transport engineering utility for modeling GTPv1-U tunneling overhead on LTE S1-U and 5G N3 interfaces, factoring in GTP, UDP, and outer IP header encapsulation.
The analyzer breaks down the full encapsulation stack: inner IP+payload + GTP header (8B) + UDP (8B) + outer IP (20B IPv4 / 40B IPv6), calculating the overhead ratio for any payload size.
Built on 3GPP Technical Specifications, ensuring accuracy for production deployments and security audits.
Calculations specifically designed to identify protocol vulnerabilities and signaling misconfigurations.
GTP-U overhead is a key consideration for backhaul transport capacity planning. Dominates for small packets like VoIP (20-byte RTP payloads). Used for S1-U and N3 link dimensioning.
