STINGA Protocol Simulator

Simulate realistic network traffic, an essential tool for network operators and service providers in ensuring QoS and QoE

Talk to us about this

STINGA Protocol Simulator simulates realistic network traffic and is an essential tool for network operators and service providers in ensuring Quality of Service (QoS) and Quality of Experience (QoE).

STINGA Protocol Simulator is a cost-efficient test tool and performs SS7 protocol simulation over TDM and IP, as well as SCTP simulation, SIP-T simulation and ISDN PRI simulation.


STINGA Protocol Simulator supports functional testing, load & performance testing, security & penetration testing, conformance testing, regression testing, mobile testing and media testing, from prototyping-stage to final product. Testing new services, products, or software versions early in the development phase saves time, prevents errors, and ensures interoperability between network elements. When commercially released and distributed, all new network elements are verified to function in a real network environment and to deliver on its premises.

Generate various traffic conditions

STINGA Protocol Simulator can generate both real network conditions and custom traffic towards specific or all parts of a network. It can also regenerate problems or irregularities that have already occurred in a real network environment. This makes error tracking and searching easier, and customer experience can easily be tested to ensure high quality.

Conformance Test Suite Frameworks are included with STINGA Protocol Simulator. These frameworks contain a large number of test scripts and templates to simulate calls, data traffic etc. towards one or several parts of a network. Test scripts and templates can easily be customized for specific tests.

Key Features

Simulator Processes

STINGA Protocol Simulator supports up to eight parallel simulator processes. These simulators can be connected to the same or to different E1/T1/J1 interfaces, and to the same or different timeslots. E.g. one of the simulators can simulate ISUP on one E1, and the other simulator can simulate SCCP on another E1 simultaneously. All simulator processes can be configured as Terminal (slave timing) and Net (master timing).

Automatic Layer 2

Layer 2 mechanisms are handled automatically. Point codes can be specified manually, or they are automatically picked up from the first incoming message. For SS7, SLTM/SLTA handshaking is also handled automatically.


Media Testing

A DTMF generator makes it possible to send and receive single DTMF tones and to specify a series of digits to be sent as DTMF tones. Received DTMF tones and audio is played in the PC-speakers. This function is available both through the user interface and from scripts.

SS7 Parameter Builder

A parameter builder simplifies the parameter building. The value of a parameter in a protocol like ISUP, SCCP, TCAP and CAMEL may be modified by dialogs reflecting the specification. For advanced or out of spec modifications, the user is able to make modifications on hex/bit level.


Script Language

A powerful and flexible script language makes it possible to set up a required/desired state, both normal and error states. There are no restrictions on neither format nor content of the messages transmitted/received. Arbitrary manipulation (down to bit level) of messages, parameters and message sequence on the different protocols are allowed. The test scripts may be started manually or they can be automatically triggered by incoming messages. DTMF scripting is supported including branching dependent on the received DTMF string. This is a very comprehensive feature for testing DTMF dependent services.

Content and order of any message of information element can be changed. The simulator can therefore simulate any regular or irregular/incorrect protocol implementation and be adapted to new protocol elements.


Conformance Test Suite Framework

Repeated use of the simulator to perform similar tests is significantly alleviated if a library structure of test scripts is built. Examples of situations where this is recommended are interconnect testing between network operators as well as functional testing, regression testing and conformance testing of terminal equipment and/or network elements. A library of test scripts is available as a framework for the user for building a dedicated test environment.
