Here's BBN's connectivity diagram: [[Image(bbn-connectivity.png)]] Here's the a snapshot of the current !OpenFlow configuration at BBN. It's very simplistic, with two VLANs, each of which is controlled by a separate controller; we aren't using the !FlowVisor to slice the network in any other interesting ways yet. [[Image(openflow-testbed.png)]] On naxos, we have: * An instance of SNAC listening on port 50811 * An instance of NOX 0.6.0 listening on port 50812 * An instance of the FlowVisor listening on port 6633 The Flowvisor configs: {{{ --> vlan811.switch Name: switch811 DatapathID: 00:00:e2:b8:dc:3b:08:11 ID: 811 --> vlan812.switch Name: switch812 DatapathID: 00:00:e2:b8:dc:3b:08:12 ID: 812 --> vlan811.guest Name: slice811 ID: 811 Host: tcp:localhost:50811 AllowedPorts: none switch812 AllowedPorts: 0-48 switch811 FlowSpace: allow: --> vlan812.guest Name: slice812 ID: 812 Host: tcp:localhost:50812 AllowedPorts: none switch811 AllowedPorts: 0-48 switch812 FlowSpace: allow: }}} On cayenne: * VLAN 811, on ports 2 and 3, with hosts camlach and chowat * VLAN 812, on ports 4 and 5, with hosts marsilikos and montreve * !OpenFlow virtual switch DPID 0xe2b8dcb0811 on VLAN 811, pointing to naxos:6633 * !OpenFlow virtual switch DPID 0xe2b8dcb0811 on VLAN 812, pointing to naxos:6633 The !OpenFlow virtual switch configs on cayenne: {{{ setvsi 811 2,3,48.811 tcp 192.1.249.133:6633 dpid 0xe2b8dc3b0811 max-backoff 15 wildcardlimit 50 setvsi 812 4,5,48.812 tcp 192.1.249.133:6633 dpid 0xe2b8dc3b0812 max-backoff 15 wildcardlimit 50 }}} The DPID on cayenne is 0x folowed by the last four octets of the MAC address of the admin interface of the switch followed by the VLAN ID. (This can be any arbitrary 48-bit number you want; I picked that convention because it seemed likely to be relatively collision-free and easy to understand.) The DPID in the FlowVisor is 00:00 followed by the last four octets of the MAC address of the admin interface of the switch followed by the VLAN ID, because when the NEC switch sends its DPID to the controller, it sends its DPID with 00:00 prepended. HP and Toroki switches use different conventions for DPIDs.
