Strategic planning tool for dimensioning Diameter Routing Agent (DRA) clusters based on total subscriber base and per-user signaling profiles across core interfaces.
DRA dimensioning sizes how many Diameter Routing Agent nodes you need from peak TPS, per-node capacity, and redundancy (often N+1), including headroom for VoLTE session binding.
This calculator aggregates per-subscriber signaling rates (Attaches, Cell Updates, Sessions) to determine the total Transactions Per Second (TPS) load. It then applies redundancy coefficients to recommend a safe node count.
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 23.203 and GSMA IR.88 benchmarks. Accounts for signaling 'rush hour' peaks and failure scenario load distribution.

Peak 8,000 TPS, vendor rating 3,000 TPS/node with TLS → ceil(8000/3000)=3 nodes active. With N+1, deploy 4. Geo-redundant pairs may double that footprint across sites.
Ratings vary widely with AVP inspection, topology hiding, and binding databases. Treat results as a planning floor pending vendor bench numbers.
A DRA is a centralized Diameter relay/proxy that routes messages between clients and servers (HSS, PCRF, OCS) based on realm, application-id, and session binding — critical in multi-vendor LTE/IMS cores.
Divide peak TPS by per-node rated TPS, then apply N+1 or geographic redundancy. Binding-aware VoLTE traffic often needs sticky routing capacity beyond raw TPS.
Typically S6a mobility events plus Gx/Gy for policy and charging. VoLTE (Rx, Cx) adds session-correlated spikes during busy hour.
