dsTest, Developing Solutions, S6b Interface, PGW, AAA

dsTest supports AAA server emulation and client interface capabilities for the 3GPP S6b Diameter interface.  The solution is ideal for customers testing a Packet Data Network Gateway (PGW) or AAA server. Test AAA and PGW S6b interfaces with our Home Subscriber Server (HSS) Emulator. Use the AAA simulation in the S6b interface application to test the capacity and performance of an HSS. Use the HSS Emulator and the Interface applications in tandem to test Diameter Routing Agents (DRA),  Proxies, Relay Agents, and Redirect Agents.

Extensible Authorization Protocol (EAP)

The S6b reference point performs authentication based on reuse of the DER/DEA command set defined in Diameter Extensible Authentication Protocol (EAP).

Implementation

The S6b application implements the following procedures:

  • Authentication and Authorization
  • Re-Authentication and Re-Authorization
  • Access Network (PGW) Initiated Session Termination
  • HSS/3GPP AAA Initiated Detach

A complete set of events that can be generated with the S6b interface application can be found here, and our Diameter Dictionary can be used to design, test, validate, and interpret the results of your Diameter testing.

As with all dsTest products, the node configurations and test scenarios are easily defined and configured with XML files that are validated against a published XML Schema to avoid invalid definitions. With our dsClient GUI, you can create, run, and archive tests, capture, graph and archive operational measurements, capture real-time data flows, and manage your dsTest servers and testing scenarios with a standalone application that runs on your PC.

Client Simulation

dsTest, Developing Solutions, S6b Interface, AAA, PGW, HSS, Client Simulation

When testing an AAA server, the S6b Interface application can be used on the PGW to test the responses of the AAA to messages from the PGW.   When used together with our SWx Interface application on a HSS client node you can provide a more complete AAA functional and load test solution.

Server EmulationdsTest, Developing Solutions, S6b Interface, Sever Emulation, AAA, HSS, PGW

A node configured with the S6b Interface application can function as an AAA Emulator providing services to the PGW over S6b in support of functional or load testing of your HSS.

When used in conjunction with the Policy and Charging Rules Function (PCRF), Online Charging System (OCS), and Offline Charging System (OFCS) emulators, dsTest can offer all of the services needed to test a PGW.

Advanced Testing Features

SmartEvents — Alter application behavior or coordinate multiple interface applications with SmartEvents. Our programmable, subscriber-level state machine gives you the ability to define handlers for specified application events that can then cause an event in another application to be executed. You can also configure handlers to modify subscriber information during run-time, introduce timers, or randomize subscriber behavior based on configurable probabilities to name a few of the many options in one of dsTest’s most powerful features.

SmartMessageElement — Insert, delete, or replace elements in Diameter, RADIUS, MAP, LDAP, GTP, REST, or SOAP messages with our SmartMessageElement solution. Define proprietary signaling or corrupt elements to facilitate negative testing. You can specify when your elements are used with SmartEvents.

Traffic Profile — Draw the shape of your test actions across time with Traffic Profile. You can define the rate for any action as a static rate or reference a Traffic Profile configuration, which also means that multiple Traffic Profiles can be running currently. Use Traffic Profile in conjunction with the randomizing features in SmartEvents to design a test that more truly simulates real-world network activity.

Diameter Dictionary — Define a set of message templates against which all messages will be validated with our Diameter Dictionary. Whether you’re load testing or testing functionality all messages are validated.

Operational Measurements

dsTest provides rich sets of measurements for the S6b interface:

  • Transaction and transport layer attempts, successes, and failures
  • Transaction duration, transactions-per-second, and round-trip delay
  • Message and byte counters
  • Errors encountered and error indications received in messages

See our Online Help for S6b measurements, EAP measurements, Diameter measurements, and socket measurements.
