Network function sizing utility for 5G Standalone Core (5GC), calculating capacity requirements for AMF, SMF, UPF, and related NFs based on subscriber density and service profiles.
5G Core dimensioning converts subscriber, session, and throughput forecasts into AMF/SMF/UPF instance counts for Service-Based Architecture deployments.
The dimensioning engine maps subscriber counts and behavior models (mobility, session activity, data rate) to transaction-per-second (TPS) and Gbps loads for each core network function, factoring in Erlang-based oversubscription models.
Built on 3GPP Technical Specifications, ensuring accuracy for production deployments and security audits.
Calculations specifically designed to identify protocol vulnerabilities and signaling misconfigurations.
Based on 3GPP TS 23.501 5GC architecture. Targets greenfield SA deployments and NSA-to-SA migration planning where core NF capacity must be validated against projected RAN subscriber growth.

2M subs, peak 0.15 attaches/sub/hour, vendor AMF rating 5k attaches/s → compute required AMF instances, then add N+1. Re-run when VoNR penetration rises.
Vendor ratings differ widely with features enabled. Treat outputs as planning floors.
Planning focus is typically AMF, SMF, and UPF scale-out from subscriber, PDU session, and throughput drivers in an SBA deployment.
Divide peak demand by per-NF capacity, then add spare instances for site or NF failure according to your availability class (often N+1 per site or geo pair).
No. Session count, DPS/PPS, and feature set (NAT, DPI, charging) can dominate before raw Gbps.
