The initial Spiral 3 GENI network core is a set of OpenFlow-capable switches in NLR and Internet2.
There are currently two standing VLANs (3715 and 3716) carried on the ten switches in the core, which are located in the nine cities shown on the maps below. Each VLAN in each provider is topologically a broken ring (to help prevent accidental loops), with the two rings in each VLAN linked in Atlanta. The gap in each VLAN is between two different links, to provide either a longer or shorter path through the core between two switches. The two VLANs are not interconnected in the core, and should not be interconnected in regionals or at GENI sites either. Sites may connect to both VLANs as long as the site keeps them separated at layer 2.
VLAN 3715
VLAN 3716
Testing / monitoring
We're in the process of setting up a process for testing the OpenFlow core from end to end, including out to campuses. VLAN 3715 has four endpoints, and VLAN 3716 has two, which we intend to connect to these campuses:
VLAN | OpenFlow Connector | Participant | Host IP |
3715 | WASH I2 | Rutgers | 10.37.15.145 |
3715 | NEWY I2 | BBN | 10.37.15.102 |
3715 | SEAT NLR | Washington | 10.37.15.90 |
3715 | SUNN NLR | Stanford | 10.37.15.3 |
3716 | HOUS I2 | BBN (later: KSU) | 10.37.16.102 |
3716 | CHIC NLR | Indiana (Gigapop) | 10.37.16.49 |
The core network status page at BBN shows whether test hosts at BBN and Stanford can ping the other test hosts right now.
For a complete list of known hosts in the connectivity subnets of these VLANs see:
KSU can't easily reach the I2 endpoint in Houston yet, so we're planning to use VLAN translation to link a host in the GPO lab at BBN to that endpoint, for now.
