Your first experiment
In this section, you will learn:
- How to create/join a project
- How to create a slice
- How to schedule your experimentation
- How to run your experimentation
If you don’t know how to access the FIBRE Portal or create your account, it’s recommended to verify START USING THE FIBRE TESTBED page.
Logging in the FIBRE Portal
To logging in the FIBRE portal, go to the portal page and click SIGN IN.

- Full user account – User account can create and manage their own projects.
Starting with Basic User Acccount
To join an existing project, log in to the FIBRE portal and access your workspace.
In this screen, you can see on the top menu an option called “Projects”. After that, click on “Request access” option.
Now you will be redirected to a list of all projects that are in the FIBRE testbed.
To select one, you can use the search bar and click on respective “Join Project” button.
After that, the owner of the project needs to approve your request.
Starting with Full User Account

To do it, click on the bottom “Request Upgrade Account”.
Now you have to in describe in details why you need the account upgrade, just click on “Submit” button and wait our approval.
After your submission was approved, you can able to see the “Create project” button.
Now you can use the project creation form, complete the form filling in this form: project name, expiration date, expiration time and a brief description of the project.
Bold Fields are required.
After completing the form, click on the “Create” button and your project can already be viewed in your Workspace.
Creating a new Slice
The project can be viewed in the “Workspace” menu.
In this menu, you will get a summary of your project information such as a number of slices, number of members and project status.
For more information click on the title of your project.
By accessing your project you can view more detailed information and you can disable it, delete it or update it.
In addition, you can view project members and remove them, create and remove slices, and start your experiments.
To create a slice, click the “Slices” tab. On this tab you will see a list of all the slices present in your project.
To create a new slice, click on the “Create Slice” button.

First, you must enter the name of the slice, a brief description of the purpose of this slice, and the expiration date/time.
After that, click on “Next to Computational Resource”.
Next, you will have to define the virtual machines. It is required the name of the VM, the hypervisor on the VM will be hosted, the template of the VM operating system and the amount of RAM.
After defining the VM parameters, you can click in the “Next to Network Resources”.
Finally, a slice summary will be present and you can review your reservation.

On this tab, you can see and text block to write your own OEDL script, or use someone of the scripts templates.
At this moment, we have two templates:
- Start Resources: initialize the resources (VMs and Flowvisor), initialize a Ryu controller in some of the VM and let you access the VMs.
- Stop Resources: shutdown the virtual machines and delete the slices of the flowvisor.
To select one script click on the combo box and select the script. You can see the script on the text block.
It is possible to edit the OEDL script to better suit your experiment.
To run the experiment click in “Run script”.
You will be redirected to the “Experiment Controller” and will be possible to see the progress of the resource allocation.
After the resources are completely up. It is possible do access the VMs by a web terminal or by using the FIBRE VPN.
To do it, go back to the “Details” tab and double click on the computer icon.
To access your Virtual Machine’s console you can click on the VM name ou on the computer icon in the topology area.
Through the console of the VM you can setup your experiment and run it.
