     11=== A. Milestones achieved ===
     12
     13The initial version of our design document was completed.  The initial
     14version of our implementation was completed, and demonstrated at the
     15seventh GENI Engineering Conference (GEC7).
     16
     17=== B. Deliverables made ===

     21 * Sensor pod implementation, February 2010. E-mailed to Vic Thomas.
     22
     23 * During GEC7 in March 2010, Puneet Sharma gave presentations about the project at the ProtoGENI cluster meeting. http://groups.geni.net/geni/wiki/Gec7ClusterCAgenda
     24
     25 * Puneet Sharma, Ethan Blanton and Sriharsha Gangam also participated in the meeting of the measurements working group: http://groups.geni.net/geni/wiki/GEC7InstMeasWGAgenda
     26
     27 * In addition, Puneet Sharma, Ethan Blanton and Sriharsha Gangam demonstrated and presented a poster on the project during the evening demo session.

     31=== A. Activities and findings ===
     32
     33We have ported the sensor pods onto the ProtoGENI platform.  A sensor
     34pod is a web-service-enabled collection of light-weight measurement
     35and monitoring sensors that collect information at a machine. This
     36information spans network properties such as connectivity to the
     37Internet, latency to some other machine in the system, and bandwidth
     38to another machine.  The sensors gather information actively (e.g.,
     39send some packets on a network link to detect available bandwidth) and
     40possibly passively.  Sensor pods are being implemented as cgi scripts
     41accessible through any web-server that supports cgi.  To enable
     42large-scale concurrent measurements, we had to modify some of the
     43measurement tools.  We leverage the web-services-based sensing pod
     44architecture to deploy various sensors measuring different metrics and
     45also to configure measurements. We currently support ping, traceroute,
     46pathrate, tulip and spruce.
     47
     48Puneet Sharma gave a presentation of our design document during the
     49ProtoGENI phone conference held on Wednesday February 24th, 2010.
     50We also gave several demos of the project during GEC7.

     55Puneet Sharma, Prakash Kumar Malligemane, HP Labs
     56
     57Unfortunately, Purdue University and HP were unable to arrive at a
     58mutually agreeable subcontract, and hence HP will subcontract directly
     59from BBN.
     60
     61=== C. Publications (individual and organizational)  ===
     62
     63Sriharsha Gangam, Sonia Fahmy, ``Distributed Partial Inference under
     64Churn,'' In Proceedings of the IEEE Global Internet Symposium, 6 pp.,
     65March 2010.

     68``On the Cost of Network Inference Mechanisms,'' IEEE Transactions on
     69Parallel and Distributed Systems (TPDS), 14 pp., accepted for
     70publication.
     71
     72The following publication from HP is under submission:
     73On Correlations between Capacity and Available Bandwidth.
     74
     75
     76=== D. Outreach activities ===
     77
     78Sonia Fahmy discussed the project with several participants attending
     79IEEE INFOCOM (the conference on computer communications) in March
     802010, and gave a related talk titled ``Evaluation: Finding your
     81Balance,'' in the panel titled ``From Shannon to Google.''
     82
     83Sriharsha Gangam presented a poster about the project at the Purdue
     84University graduate student poster session in March 2010.
     85
     86Sonia Fahmy served on the technical program committee (TPC) of
     87SIGMETRICS 2010, and reviewed several measurement and testbed-related
     88papers.  Puneet Sharma served on the TPC of COMSNETS 2010 and reviewed
     89several measurement architecture-related papers.
     90
     91=== E. Collaborations ===
     92
     93We participated in all bi-weekly Cluster C conference calls held since
     94January 2010.
     95
     96During the seventh GENI Engineering Conference, we discussed the
     97project with other measurement projects that started in spiral 2 and
     98those that had started in spiral 1. We discussed common aspects with
     99the teams from University of Kentucky, University of Wisconsin, and
     100the Ohio State University.
