Milestone ORBIT: 1e Establish OMF operating environment, verify, and demo

e) Establish OMF operating environment for your stationary and mobile testbeds, verify with experiments, and demo at a GEC. (6-12mo)

Per 1Q09 QSR, completed 3/31/09:

We have achieved the following deliverables in this quarter: a) Extend OMF to support multiple heterogeneous testbeds, anticipating GENI control framework structures where possible, and integrate into your testbeds. (6mo) b) Extend OMF interfaces and software to support mobile testbeds by: distributing experiment scripts to mobile nodes; providing local caching of experiment results during disconnection; and by executing experiment actions at predefined points in time (timebased orchestration). (8 mo) e) Establish OMF operating environment for your stationary and mobile testbeds, verify with experiments, and demo at a GEC. (6-12mo) Deliverable b) was achieved early, in time for the GEC demo. Activities and Findings Work on the three milestones listed above culminated in a demonstration of a wireless throughput measurement experiment on a vehicular testbed at the recent GEC. The experiment measures throughput between a Wifi interface inside the vehicle and a stationary access point located inside the Winlab building as the vehicle moves. A second Wifi connection is used for control (experiment configuration and measurement data). The experiment script is installed over this control link in the vehicle at the start of the experiment. When the control connection becomes disconnected during the experiment, results are cached in the vehicle, and the experiment proceeds as governed by the time-orchestrated experiment script. When the control connection is reestablished, the cached data is uploaded into the OMF measurement repository. The same experiment script can also be executed on the stationary ORBIT testbed or the stationary testbed at NICTA. Thus, this demonstration showed OMFs capability to support multiple heterogeneous testbeds.
