    v5 v6  
    44no radar control via Xen. Due February 1st, 2009.

    67The Orca control framework comprises a set of three distinct actor servers that correspond to GENI Experiments,
    78Clearinghouses, and Aggregate Managers 1. GENI experiments correspond to Orca service managers,
     
    1112an Orca site authority within the same Java virtual machine that communicate using local procedure calls.

    1315The Orca actor servers run on a gateway node connected to both the public Internet (otg.cs.umass.edu) and the
    1416sensor node on the roof of the UMass-Amherst CS department. The sensor node on the UMass-Amherst roof, in

    2023Each node is primed with the software necessary to create Xen virtual machines and sliver their resources. The
    2124local storage is a 32gb flash drive partitioned using logical volume manager. The Orca node agent snapshots a
     
    2326tc is installed on each node to shape and limit each experiment’s network traffic.

    2529Using the default Orca web portal, users are able to login and request slices on the ViSE testbed. Currently,
    2630only the sensor node on the CS roof is accessible by end-users. We have decided to wait until the end of winter to
     
    2832We expect to access them in early-to-mid April depending on the weather and the snow melt.

    3035In addition to the software to support Orca, each node has the appropriate foundation software/drivers to
    3136operate the sensors, wireless and wired NICs, an attached Gumstix Linux embedded control node, and a GPRS

    3945The milestone is a pre-cursor to our sensor virtualization work. While users are able to create slices composed
    4046of Xen virtual machines bound to slivers of CPU, memory, bandwidth, and local storage, they are not able to access
