eChallenges e2006 Large scale interoperability, integrating the Daidalos project

Large scale interoperability, integrating the Daidalos project Frances Cleary Grant Miguel Ponce de Leon TSSG – Waterford Institute of Technology Ireland

Daidalos WP5
Daidalos (49 partners), integration was an immense task
co-ordinated and implemented by WP5.
Tasks Included
Defining Integration Processes and Models
Defining conformance test Specifications
Test Site Planning,Deployment and Integration
Test planning/scheduling/status report documentation
Test case execution, fault detection, result reporting.

Daidalos WP5 Task Forces
The Integration of WP innovations were completed
through the selected ‘Nidaros’ Scenario.
To evolve and implement this scenario, task forces were created
Scene analysis Task Force (Input from all WP’s)
Scene Step analysis Task Force (Input from WP5 step responsible)
Mapping and Deployment Task Force

Daidalos Integration Model
Due to the complexity of the Daidalos Architecture, the integration model addressed the following main areas
Integrated Testbed (2 integrated test sites)
Sophia Antopolis,France
Aveiro, Portugal
Integration-oriented developments
Intra work package integration activities
Formalisation of Integration roles and processes
Identification of best Integration and Testing strategy (i.e. sandwich testing)
Conformance Test Specification
Identification of Nidaros specific WP interfaces
Definition of Scenario specific Conformance tests

Daidalos Integration Management
Roles created for successful Integration management
Test Manager (one from each technical WP)
Responsible for defining Nidaros conformance Test cases (including interface tests)
Build Manager (one from each technical WP)
Responsible for WP code builds, and corresponding documentation.
Responsible for WP deliveries, following delivery process outlined by WP5.
Test Site Manager
Organise Test schedule (Daidalos ~organisation approx 100 people at test site)
Responsible for the provision of required and specialised hardware and installing software components

Daidalos Test Methodology
Test Case Definition
Test Case Naming (e.g. N3:01)
,Systems under test, test summary,
API’s & interfaces involved,
initial conditions
Test Report
Verdicts, person executed test,
any closure actions and impacts,
comments and possible actions
to be performed if test fails.
Test Case No N3:01 SubSystems/Systems UnderTest (SUT) WP3 MMSPP Subystem/WP4 Subsystems/ NEWSCAST Application Components involved MMSP UA MMSP P/B Streaming Server NEWSCAST & VoIP Application Rules & Event Management, Context, Personalisation Protocols/APIs/IFs involved Intra WP3 Intra WP4 Intra Subsystem EIF0: MMSP UA-MMSP P/B (SIP) CM/P/REM Inter WPs WP3-WP4 MCCS Test Summary: Newscast that was on hold in Car PC unholds when VoIP call terminates but resumes voice only because Bart is driving.

Daidalos Integration Testing
Validation of the Nidaros Integrated Demonstrator conformance tests
Sophia Antopolis in November 2005 , Aveiro in March 2006.
The 1st validation could only produce very high-level results (i.e. pass/fail of TC).
As issues were resolved we were able to validate the demonstrator at a much lower level of detail.
Conformance session in Aveiro up to 120 test cases were planned, based on the Nidaros Test case specifications.

Integration Issues Encountered
Unstable MIPv6, switch from Mandrake to Ubunto
Machines crashing and rebooting became time consuming.
Minor Errors encountered, led many times to major complications.
Initial steps and configurations unforeseen eroded into valuable scheduled testing allocated time.

Conclusion and Results
Communication was a main issue encountered during integration
Using Ubunto, MIPv6 became a lot more stable.
Key point - developers to meet iteration delivery deadlines
Scenario step planning contributed positively to the integration process.
The 1st successful integrated testing utilising all Work packages took place at Aveiro.
