There are high requirements on efficient and flexible load tests. They have to fullfil very high request rates and need to be executed time synchronized during the test campaign execution.The TBL project has the goal of realizing a test system capable of testing the performance indicators of network elements during their operation. The Test System verifies the performance parameters by sending a huge number of requests in a short period of time. It is designed for testing in special the UMTS, GPRS, GSM, SS7 and ISDN (PRI and BRA) connections. The performance test suites are written in TTCN-3; for the execution of the test campains we use the TTman platform developed by Fraunhofer FOKUS and Testing Technologies.

Goals

It is the aim of this project to design, implement and apply a TTCN-3 based load test system for various network elements in UMTS, GPRS, GSM, SS7 and ISDN.

Technology

In TBL key roles are assigned to international standards by ETSI:

• TTCN-3 (Testing and Test Control Notation)
• TRI (TTCN-3 Test Runtime interface)
• TCI (TTCN-3 Test Control interface)

Tests are executed by using the TTCN-3 tools from Testing Technlogies.
