2. Virtual wall

3. Advanced Functionalities
Impairment/link emulation
Start up scripts
XEN VMs on Virtual Wall 2
Shared vlans
Connectivity: stitching

4. Upscaling experiment with shared vlans

5. Example: SME does scalability testing

6. Using shared lans

7. Sharedlan <link client_id="link2">
<component_manager name="urn:publicid:IDN+wall2.ilabt.iminds.be+authority+cm"/>
<link_type name="lan"/>
<sharedvlan:link_shared_vlan name=“shared_lan_link3"/>

8. Advanced examples

9. Openstack RSpec Scale up when needed
Experimenters can use exactly the same for own private clouds
“cloud-on-demand” service (with size as they want)
Including all other testbeds and connectivity of the F4F federation

10. Openstack instance

11. iMinds’ Tengu platform – Fed4FIRE services Create services on top of testbeds
Cloud-on-demand
Hadoop/Storm/Lambda

12. International federation and connectivity

13. Layer 2 connectivity = stitching VLANs
AUTOBAHN
SDX
STATIC
VLANS
Meshed L2 connections possible SDX = software defined exchange eases connectivity (=exchange) VLAN translation needed + SDN functionality

14. Stitching workflow: iMinds to Illinois
1. Experimenter draws layer 2 link
Stitching Computation Service (SCS)
3. Tool contacts SCS
to know the path
and SCS sends back the path and workflow
(e.g. some networks can do VLAN translation)
2. and starts provisioning
Wall1
Wall2
Geant
Internet2
Illinois
4. Tool provisions at all testbeds and networks
through the aggregate manager API
and negotiates the VLAN IDs
Wall1
Wall2
Geant
Internet2
Illinois
5. User logs in
and can ping

15. SCS per federation
