2 Roadmap Motivations Introduction The GO4IT IPv6 Test Tool Services Demo of executable test suite Q&A 17/04/2007 Go4IT

3 Motivations (I): The need for IPv6 Conformance Testing Interoperability was one of the most important reasons for IPv4's success and is a key feature of IPv6 Conformance Testing can provide a first step towards ensuring interoperability and can be also helpful in identifying and resolving interoperability issues 17/04/2007 Go4IT

4 Motivations (II): State of the Art Conformance Testing solutions for IPv6 exist and are available, but Interoperability-oriented and less formal (e.g. TAHI) Proprietary or linked to large tool chains TTCN-3 ATS for IPv6 exist and are available for free Follow ISO-9646 methodology Large coverage of IPv6 Validated by ETSI STF 276 No freely available execution environment makes purchase of commercial tool compulsory for execution (e.g. Testing Tech's IPv6 Test Suite + TTworkbench) Existent tools are TTCN-3 Development Tools in the broader sense, i.e. IDE, Execution Environment, Test management etc. 17/04/2007 Go4IT

5 Motivations (III): Immediate Objectives There is a need for Low-Cost and "Open" TTCN-3 based IPv6 Conformance Tests IPv6 conformance verification services based on those tests would be very helpful for organizations not willing or able to setup own test bed Go4IT project addresses both issues as Immediate objectives 17/04/2007 Go4IT

6 Motivations (IV): Long-Run Objectives Sometimes, possibility of modifying existing tests or developing new ones might be required. GO4IT market analysis also identified need for free or low-cost TTCN-3 test development tools TTCN-3 compiler TTCN-3 editor/ide TTCN-3 CoDec generator GO4IT Long-run Objective: Provide an open-source TTCN-3 test development environment (Goal 3) 17/04/2007 Go4IT

7 Motivations (V): GO4IT Objectives Go4IT Project Immediate Objectives Executable Tests Services GO4IT Long Run Objectives TTCN-3 Open Source Community, Tools and Platform 17/04/2007 Go4IT

9 GO4IT IPv6 Test Suite: Overview & Status Go4IT IPv6 Test Services (Downloads, Validation) GUI CUI TTCN-3 Runtime TE 1 Compiled ETSI TE IPv6 Core ATS TE 2 Compiled ETSI TE IPv6 Core ATS Adaptation 1 Adaptation 2 17/04/2007 Go4IT

10 GO4IT IPv6 Executable Test Suite: License and Conditions Based on Testing Technologies (TTworkbench) TTCN-3 Runtime Kernel LGPL License Partly Open Source Low license fee to Testing Technologies for Kernel and Adaptation Layer GUI/CUI and Runtime libraries open source Full services infrastructure for smooth handling of licensing and packaging is in preparation 17/04/2007 Go4IT

11 GO4IT IPv6 Test Suite: Requirements JAVA (GUI is JAVA application based on Eclipse SWT Libraries) LibCap Library for accessing IP-Layer information from OS IPv6 Implementation to be tested (e.g. Node, Router) 17/04/2007 Go4IT

12 Achievements and Perspectives (I) Generic architecture to support different platforms (JAVA, C++) Open TTCN-Standard (TRI/TCI) Compliant Test Execution environment Integration of UI-Implementations with Test Execution Environment successful Showcase demonstrating openness of Architecture Windows and Linux supported 17/04/2007 Go4IT

13 Achievements and Perspectives (II) Graphical and Command-Line Test Management User Interfaces with following features: Test campaign managment Test Parameters management Test Execution Control Test Logging Graphical/Textual Online/Offline Test Results Reporting Test Verdict Analysis, Test Data Analysis 17/04/2007 Go4IT

14 GO4IT IPv6 Executable Test Suite : ATS Modules (I) Group of Tests Description Testcases Status IPv6 Core Functionalities For testing IPv6 Core Functionalities (Stack initialization, Packets generation and processing, Jumbograms etc.) 505 Ready IPv6 Mobility For testing IPv6 Mobility Functionalities. Neighbor discovery 160 Expected End of Oct IPv6 Security ASH, ESP etc. 10 (AH) 23 (ESP) Expected End of Oct /04/2007 Go4IT

15 Demo Executable test suite for IPv6 Graphical User Interface (GUI) Command-Line User Interface (CUI) 5 Test modules featuring a total of 268 Testcases 17/04/2007 Go4IT

16 Outlook: GO4IT Continueing work on improving the Executable Test Suite Work on C++ TTCN-3 compiler and Test engine making good progress DHCPv6 Testsuite under development (IRISA) Full Service Deployment 17/04/2007 Go4IT

17 Outlook: Beyond GO4IT Project The introduction of IPv6 creates new challenges and chances for application layer architectures and protocols (SoA, IPTV, IMS) E.g. New use cases (TTCN-3)Testing for such architectures and protocols on top of IPv6 stacks is still new R&D field. 17/04/2007 Go4IT

18 Executable Test Suites: Summary Go4IT IPv6 Test Suite is already available and ready for use Download it from and try testing with it! Support and guidance also provided Join open source project to enhance the tools being developed 17/04/2007 Go4IT
