Loading Calculator...
The definitive engineering tool for dimensioning loss systems (M/M/c/c). Calculate the Grade of Service (GoS) or required circuit count for a given offered traffic load in Erlangs.
The Erlang B formula assumes that blocked calls are cleared (not queued). It uses the provided traffic load (Arrival Rate × Mean Holding Time) divided by the circuit count to solve for the recursive loss probability.
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 ITU-T E.500 recommendations. Ideal for dimensioning non-hierarchical circuit-switched networks and SIP trunking gateways.
