GENI Racks and Meso-scale OpenFlow Interoperability

This page describes an interoperability experiment that has been completed between Meso-scale OpenFlow sites, ExoGENI, and InstaGENI OpenFlow Resources. This experiment used the OpenFlow VLAN 1750 at each Meso-scale site and the GENI Core OpenFlow VLAN 3716. This experiment reserved the following resources:

ExoGENI:

  • Two BBN ExoGENI rack VMs on OpenFlow shared VLAN 1750
  • Two RENCI ExoGENI rack VMs on OpenFlow shared VLAN 1750
  • Two BBN Campus VMs that have access to OF VLAN 1750 via flowspaces through the ExoGENI rack OF switch. (These OF flowspaces are managed with the ExoGENI FOAM aggregate).

InstaGENI:

  • Two InstaGENI rack VMs on OpenFlow shared VLAN 1750
  • Utah PG Campus host that has access to OF VLAN 1750 via flowspaces through the InstaGENI rack OF switch. (These OF flowspaces are managed with the InstaGENI FOAM aggregate.)

Meso-scale:

  • Three meso-scale OpenFlow Aggregates: Rutgers, BBN and Clemson.
  • Three meso-scale compute resources sites: 1 WAPG at Rutgers(Internet2), 1 MyPLC at BBN, and 1 MyPLC at Clemson (NLR).
  • NRL and Internet2 OpenFlow VLAN 3716 is used for all hosts in experiment1 to exchange traffic

The following diagram describes the Meso-scale and GENI Racks interoperability experiment captured in this page:

Acceptance Tests are taking place for both GENIRacks projects. For details, see the following pages:

Omni configuration settings

The Omni configuration defined the pgeni.gpolab.bbn.com slice authority to be used for the credentials. To simplify the experiment setup, the following aggregate manager nick_names were defined in the omni_config:

Interoperability Experiment

The following command was issued to create the slice used for this interoperability experiment:

 $ omni.py createslice interop 

ExoGENI Resources

 $ omni.py createsliver interop -a exobbn interop-2vm-shared-vlan-exo-bbn.rspec

The RSpec used: interop-2vm-shared-vlan-exo-bbn.rspec

The following sliver was created to reserved the 2 RENCI ExoGENI VMs on shared VLAN 1750:

 $ omni.py createsliver interop -a exorci interop-2vm-shared-vlan-exo-rci.rspec

The RSpec used: interop-2vm-shared-vlan-exo-rci.rspec

The following sliver was created on the BBN ExoGENI FOAM aggregate to allow both the rack VMs and the local campus resources to connect to VLAN 1750:

The RSpec used: interop-openflow-exorci.rspec

InstaGENI Resources

The following sliver was created to reserve the 2 Utah InstaGENI VMs on shared VLAN 1750:

 $ omni.py createsliver interop -a ig interop-2vm-shared-vlan-insta-utah.rspec

The RSpec used: interop-2vm-shared-vlan-insta-utah.rspec

The following sliver was created to reserve one Utah PG VM on shared VLAN 1750:

 $ omni.py createsliver interop -a pg interop-1vm-shared-vlan-pg.rspec

The RSpec used: interop-1vm-shared-vlan-pg.rspec

The following sliver was created on the InstaGENI FOAM aggregate to allow both the rack VMs and the local campus resources to connect to VLAN 1750:

 $ omni.py createsliver interop -a of-ig interop-openflow-insta-utah.rspec

Run Experiment

Determine which ExoGENI VMs have been assigned to you at each site. Note that for the ExoGENI racks the list of assigned compute resources can be found with the omni listresources command:

 $ omni.py listresources interop -a exobbn -o
 $ omni.py listresources interop -a exorci -o 

Determine which InstaGENI Utah rack VMs have been assigned to you. Note that for the InstaGENI rack, the list of assigned compute resources can be found with the omni sliverstatus command:

 $ omni.py sliverstatus interop -a ig -o

Determine which PG Utah site VM was associated with VLAN 1750:

 $ omni.py sliverstatus interop -a pg -o 

Determine which hosts have been assigned to you for each of the meso-scale sites:

 $ omni.py sliverstatus interop -a pg2 --api-version 2 -t GENI 3 -o 
 $ omni.py sliverstatus interop -a plc-bbn -o 
 $ omni.py sliverstatus interop -a plc-clemson -o 

The output files created by the listresources for ExoGENI and the sliverstatusfor InstaGENI include a "hostname" for each allocated compute resource. Additionally for the PG and InstaGENI VMs there is a port number required to connect.

Using information determined from the listresources and sliverstatus commands, was able to login into each compute resource shown in the diagram above and exchanged traffic between all Meso-scale, InstaGENI and ExoGENI compute resources, including the campus resources which were configured to pass through the racks OF Switch.
