MEGACO Signaling Tester

Test Harness & Test Suite for the Validation of MEGACO Implementations.

MEGACO Conformance Test Architecture

Overview

The MEGACO Signaling Tester is a test environment for the MEGACO signaling specification as defined by the IETF standards.  It is a SAFIRE based test harness able to run pre-defined ACATS test scenarios against MEGACO test objects in a controlled & deterministic manner.

The SAFIRE graphical editor allows new scenarios to be created or existing scenarios to be modified using the MEGACO interface library (API), which defines the MEGACO messages and parameters. The test harness includes a MEGACO protocol analyzer for on-line capture and decode of the signaling in real-time both during tests and as a stand-alone tracer for live systems.

The MEGACO Signaling Tester is suitable for conformance tests, functional tests, factory tests & acceptance tests.

Key Features

• Fully integrated, complete test environment for MEGACO
• ISO conformant test scenarios giving framework coverage of MEGACO
• Graphical development environment & libraries for creating new MEGACO tests
• Compatible with ACATS MEGACO Professional Test Suite (not included)
• Expandable for SIGTRAN, SIP, ISDN, ISUP-MEGACO interworking
• MEGACO Reference Test Object

Description

The MEGACO Signaling Tester was designed to be a complete solution for MEGACO signaling test requirements.  It has the key components:

• MEGACO Test Harness including codec & IP stack
• ACATS MEGACO Framework Test Suite
• MEGACO Interface Library
• MEGACO Protocol Analyzer

The MEGACO test harness uses the powerful SAFIRE environment to provide advanced features like

• Graphical editing (flow diagram representation)
• Automated execution of test campaigns
• Slow motion replay with synchronized trace & breakpoints
• Test reports with statistics (also HTML)
• Real-time, high performance protocol analysis

Using the MEGACO Signaling Tester, test objects can be accurately, reliably and comfortably validated for compliance with published ETSI TS 102-374-2 (2004/11) standard.  It is suitable for manufacturers, network operators and service providers to address all stages of the development cycle, regression testing through to type approval, acceptance testing & certification (note: requirements may be country/organization specific).

The ACATS MEGACO Framework Test Suite includes test scenarios for the validation of terminal equipment by simulating the controlled interaction with other MEGACO entities such as

• Media-Gateway (MG)
• Media-Gateway Controller (MGC)

SAFIRE Editor Sample

The framework test suite contains a selection of important scenarios, which can be used to confirm the basic functionality of a MEGACO test object. They are also an excellent basis for customization and enhancement according to specific needs.

An upgrade is available for the ACATS MEGACO Professional Test Suite, which offers extensive coverage of the MEGACO signaling test requirements.

MEGACO Reference Test Object

For reference a virtual test harness is included, that allows test scenarios to be run off-line against a software-only test object under controlled conditions.  The test harness uses a software bus to replace the physical connection and an accurate software model as the test object.  Normally fully automated execution of tests is possible, but in some specific cases the test object allows/requires user interaction during the tests.
