Experimentation Procedure

How to get involved

Step 1

The VITAL-5G experimentation process is represented in the Figure below.

Vertical Service Design. This phase has the objective of designing and implementing a vertical service to be experimentally validated in one of the testbeds offered by VITAL-5G (for more information on each testbed and its available resources visit the links at the start of the page).

Experiment Design. This phase has the objective of defining an experiment for the validation of Network Applications or vertical services in a VITAL-5G testbed. The experiment is defined through an Experiment Blueprint (ExpB), which follows the format of 5G EVE experiment blueprints.

Preparation of 5G testing environment. This phase has the objective of preparing the testing environment for the execution of an experimentation campaign and, depending on the complexity of the scenario, it may require the manual intervention of the testbed administrators, in terms of 5G network settings or T&L facility configuration.

Vertical Service Instantiation. This phase has the objective of provisioning the vertical service in the target testbed, triggering the instantiation of its NetApps in the virtual infrastructure, their activation and configuration. If the Network Applications composing the vertical service are associated to restrictive software licenses (e.g., related to the number of instances that can be executed concurrently), these licenses are properly verified and validated.

Experiment Execution. This phase has the objective of executing the experiment and collecting the monitoring data required to evaluate the performance of the service. During the experiment execution, some test scripts can be automatically configured and executed by the platform. Moreover, the user will have access to the various Network Applications’ components, with the possibility to operate directly on their internal processes. In parallel, the mechanisms offered by the orchestrators in VITAL-5G testbeds, exposed through suitable APIs, will give the possibility to operate on the lifecycle of the vertical service.

Vertical Service Evaluation. This last phase has the objective of helping the experimenters in the evaluation and assessment of the vertical service performance in the 5G network. Elaborating the monitoring data and the network and service KPIs collected during the experiment execution phase, the platform analyses the results generating experiment reports.
