| 1 | The ORBIT Cluster met at the GEC on Monday July 20 and Tuesday July |
| 2 | 21. At the July 20 meeting Max Ott and Ray Raychaudhuri gave an |
| 3 | overview of the ORBIT testbed and discussed the integration of WiMax |
| 4 | base stations into the cluster. An initial deployment at Rutgers is |
| 5 | complete and baseline performance measurements have been collected. |
| 6 | The July 21 meeting was less structured and included dicussions of |
| 7 | topics and issues raised by the meeting participants. |

| 9 | Topics discussed at the ORBIT CF meetings: |
| 10 | * ORBIT is not and does not claim to be a full-fledged control |
| 11 | framework. It is best viewed as a GENI aggregate. The ORBIT team |
| 12 | would like guidance from the GPO on which cluster they should work |
| 13 | with. They do not want to be developing and maintaining software |
| 14 | needed to talk to all other control frameworks. Integration with |
| 15 | the ORCA control framework is their next step. |
| 16 | * ORBIT OMF might be able to serve as a GENI aggregate manager. |
| 17 | * The ORBIT experiment controller can be used to control |
| 18 | experiments on PlanetLab. An ORBIT experiment can now include |
| 19 | PlanetLab nodes. |
| 20 | * There was some discussion around integration of the Clemson |
| 21 | testbed. This testbed includes embedded wireless platforms with |
| 22 | 802.16 radios but not operating at WiMAX frequencies. The Clemson |
| 23 | testbed includes mobile nodes that can travel a high speeds on a |
| 24 | BMW test track. |
| 25 | * ORBIT OMF is being extended to handle mobility. |
| 26 | * Concerns specific to wireless testbed such as ORBIT: scheduling |
| 27 | and slicing of testbed resources so experiments don't interfere; |
| 28 | conforming to rules by the FCC and other similar regulatory |
| 29 | bodies; protecting measurement devices from badly behaved |
| 30 | experiments. |
| 31 | * Issues with using !OpenFlow in a testbed where flows are not |
| 32 | persistent. For example, when vehicles more in and out of range |
| 33 | of a base station. |
| 34 | * ORBIT can be used to do experiments based on DTN (Disruption |
| 35 | Tolerant Networking) technologies since every node as processing |
| 36 | and storage resources. |
| 37 | * MIT is interested in using ORBIT for network coding |
| 38 | experiments. They want to push networking coding as close to the |
| 39 | physical layer as possible. They will work with Rutgers to |
| 40 | determine the feasibility of such experimentation. |
