SCTP Signaling Tester

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

SCTP Conformance Test Architecture

Overview

The SCTP Signaling Tester is a test environment for the SCTP signaling specification as defined by the IETF standards. It is a SAFIRE based test harness able to run pre-defined ACATS test scenarios against SCTP 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 SCTP interface library (API), which defines the SCTP messages and parameters. The test harness includes a SCTP 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 SCTP Signaling Tester is suitable for conformance tests, functional tests, factory tests & acceptance tests.

Key Features

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

Description

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

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

The SCTP 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 SCTP Signaling Tester, test objects can be accurately, reliably and comfortably validated for compliance with the IETF RFC 2960, 3309.  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 SCTP Framework Test Suite includes test scenarios for the validation of terminal equipment by simulating the controlled interaction with other SCTP entities such as

• SIGTRAN Signaling Gateway (SG)
• SIGTRAN 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 SCTP test object. They are also an excellent basis for customization and enhancement according to specific needs.

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

SCTP 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.
