Diameter is an authentication, authorization, and accounting protocol used pervasively in telecom and datacom networks. Diameter protocol signaling load is increasing due to subscriber growth. Operators need to prove their networks can scale reliably and have the necessary capacity and built-in redundancy. Network equipment manufacturers (NEMs) need to test at all stages of the product life-cycle and conduct acceptance testing at the operator. The Valid8 Diameter Load Tester provides testing capabilities across numerous Diameter interfaces in fixed and mobile networks such as Cx, Dx, Ga, Gd, Gx, Gy, Nasreq, Rf, Rx, S6a, S6c, S6m, S6n, S6t, T6ai, T6bi, Tsp.
It can test fuzzing, security, feature and performance on single or multiple Diameter interfaces concurrently, generating tens of thousands of transactions per second (scalable per machine), with customizable message flows and content.
Diameter Load Tester comes with pre-canned scenarios which can be tailored to specific requirements.
Security test option includes:
HSS, PCRF, MME, IWF-AAA
User commands can be fully automated using the HTTP API. This includes performing all test control functions as well as collecting results and metrics.
The application’s subsystems can be edited directly in the browser using TDL or by using the graphical tools. The Message Workshop allows for creating of test scenarios directly from the hex stream of a remote capture, while the Graphical Editor (on the feature roadmap for 2019) will allow for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.
For testing the HSS Server, the Valid8 Tester can generate S6a, Sh Diameter traffic to test performance and stability.
For testing the PCRF, the 4G Network Emulator can wrap around the PCRF with the core network and IMS.
The Valid8 Diameter Load tester is capable of simulating multiple nodes and generating large scale stateful Diameter load
