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 was used at each Meso-scale site and the GENI Core OpenFlow VLAN 3716. In this experiment the following resources are reserved:

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:

Omni configuration settings

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

Interoperability Experiment

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

 $ omny.py createslice interop 

ExoGENI Resources

The following sliver was created to reserve the 2 BBN ExoGENI VMs on shared VLAN 1750:

 $ omny.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:

 $ omny.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:

 $ omny.py createsliver interop -a of-exobbn interop-openflow-exobbn.rspec

The RSpec used: interop-openflow-exobbn.rspec

The following sliver was created on the RENCI ExoGENI FOAM aggregate to allow the rack VMs to connect to VLAN 1750:

 $ omny.py createsliver interop -a of-exorci interop-openflow-exorci.rspec

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:

 $ omny.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:

 $ omny.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:

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

The RSpec used: interop-openflow-insta-utah.rspec

Meso-scale Resources

The following slivers were created get compute resources at each of the Meso-scale aggregate mangers (Rutgers, BBN and Clemson):

 $ omny.py createsliver interop -a pg2 --api-version 2 -T GENI 3 interop-wapg-rutgers.rspec
 $ omny.py createsliver interop -a plc-bbn interop-myplc-bbn.rspec

Run Experiment

Determine which ExoGENI VMs have been assigned to you:

 $ omny.py listrsources interop -a exobbn -o
 $ omny.py listresources interop -a exorci -o 

Determine which InstaGENI Utah rack VMs have been assigned to you:

 $ omny.py sliverstatus interop -a ig -o

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

 $ omny.py sliverstatus interop -a pg -o 

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

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

The output files created by the listresources and sliverstatus commands in this section 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 and exchange traffic between all Meso-scale, InstaGENI and ExoGENI compute resources, including the campus resources which were pass through the racks OF Switch.
