Daidalos Framework for successful Testbed Integration 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.
Steps leading to Integration
Integration Tasks
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.

Nidaros Scenario WP2 Innovations WP3 Innovations WP4 Innovations The Integration of WP innovations were completed through the selected ‘Nidaros’ Scenario.

Nidaros scenario
Describe nidaros scenario

Daidalos WP5 Task Forces
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
Test Case Definition : Test Case Naming (e.g. N3:01), 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.

Daidalos Physical Deployment

For European based conferences the daidalos testbed was setup in a mobile Science Truck which demonstrated Daidalos Innovations.

Daidalos Visualisation
Virtualisation Tool (DLR)
Figure 8 we have shown the layout for the CarPC view (a similar view was prepared for the PDA view) after some messages have been passed. It shows the simulated status of the network components and the messages from the major WP4 subsystems and third party services. The colour of the arrows indicates the presence of recent message traffic over these connections.

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).
- Problems related to network layer, Mobile IP and WP2 network drivers which were unstable
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 Testing
Example Test Case
Bart is driving on the motorway, which triggers the launch of the Traffic information Service. Bart arrives at the airport, and continues to drive towards the car parking area of the airport. His car system screen shows the airport information carrousel. Information about all flights will be shown. Bart parks and leaves his car, taking his PDA with him. A transfer is invoked on the transferring components in the old service and starts the new service on PDA and stops the old service on CarPC. The airport arrivals information can now be seen on Barts PDA as he enters the airport arrival terminal.

Integration Issues Encountered
Unstable MIPv6, switch from Mandrake to Ubuntu
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
All tests performed on the test-bed successfully used Mobile IP, which remained very stable on Ubuntu in comparison to earlier attempts at using mobile IP on top of Mandrake.
WP2 WLAN drivers were relatively stable compared to their earlier performance in Sophia.
Route Optimisation worked over Mobile IP, with very noticeable performance improvements as compared to earlier tests on WP4 standalone test-beds.
Registration module and several other components were dummy’s because of lack of integration on Ubuntu (previously worked under Mandrake).
Communication was a main issue encountered during integration
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.
