It is possible to connect Grid'5000 resources to resources from other testbeds part of Fed4FIRE or GENI. This is implemented by stitching (bridging together) global KaVLAN vlans to VLANs connected to the imec SDX.

This is slide 16 from this presentation.

Grid'5000 is connected to the Iminds SDX (now imec SDX), hosted in Ghent (Belgium). That SDX is also connected to other SDXes, which means that you should be able to connect your Grid'5000 nodes to e.g. Cloudlab nodes. This is implemented using a stitcher service.

Step by step process

On the Fed4FIRE side

  • Get Fed4FIRE credentials. You can request an account as part of the grid5000 project.
  • Use the jFed tool (Fed4FIRE's client) to reserve resources on Fed4FIRE.
  • Include a Dedicated Ext. Network Connection, and choose one of the Grid'5000 VLANs (1290-1294).
  • Start your experiment

On the Grid'5000 side

  • Reserve nodes, and a global KaVLAN. Deploy your nodes. For example:
oarsub -t deploy -l "{type='kavlan-global'}/vlan=1+nodes=1,walltime=0:30" -I
kavlan -V # => 15
kadeploy3 -e debian9-x64-min -f $OAR_NODEFILE -k --vlan 15

Stitching the global KaVLAN with the SDX VLAN

You need to interact using the stitcher service API. Example commands are:

  • List all stitchings:
curl  https://api.grid5000.fr/3.0/stitcher/stitchings
  • Add a stitching between KaVLAN VLAN 14, and SDX VLAN 1291:
curl -d '{"id":"14", "sdx_vlan_id":"1291"}' -H "Content-Type: application/json" -X POST https://api.grid5000.fr/3.0/stitcher/stitchings
  • Remove the stitching for KaVLAN VLAN 14:
curl -X DELETE https://api.grid5000.fr/3.0/stitcher/stitchings/14
  • For debugging purposes, the stitcher's network configuration is visible with:
curl https://api.grid5000.fr/3.0/stitcher/network_configuration
