Federation Computing Interface (FCI): An API for accessing resources of the federation
In many testing scenarios there is a need to configure resources or even get monitoring status data properly after the experimentation scenario(slice) is provisioned while the testing is in progress. What is critical with the operational part of a experimentation scenario is the proper and valid run-time configuration of the participating resources. The reason is that, while the experimentation scenario is operated by the federation’s experimenter the federation must ensure all terms of the requested SLA of the experimentation scenario are fulfilled and nothing is violated or falls out of the scope of the SLA. To this end, the SLA must be constantly audited (or monitored) for different parameters (i.e. metering, service quality, security, etc).
Federation Computing Interface (FCI) is an API for accessing resources of the federation. It is an SDK for developing applications that access experimentation scenario's requested resources through the broker services during operation of testing. It is quite easy to embed it into your application/ SUT in order to gain control of the requested resources during testing.
FCI allows the User-Application/SUT to access the testbed resources during execution of the experiment in order to manage and configure various environment parameters or to get status of the resources.
In brief these are the requirements and the process:
- FCI is an Eclipse based SDK.
- You need to download the FCI plugins and the FCI Core libraries and install
- You need to modify your application (SUT) to access resources in the federation (if you need to do this) according to your initial experimentation scenario request
- Execute your application either at your premises or inside a resource
- You can also operate the requested experimentation scenario even from another application while your tests execute (i.e. external triggers)
