    v3 v4  
    11 Milestone 3. Initial Orca integration. Xen and Orca software running on three sensor nodes, non-slivered,
    22no radar control via Xen. Due February 1st, 2009.
     3[[BR]]
    34The Orca control framework comprises a set of three distinct actor servers that correspond to GENI Experiments,
    45Clearinghouses, and Aggregate Managers 1. GENI experiments correspond to Orca service managers,
    … …  
    78remote procedure calls. The ViSE project has setup one instance of an Orca service manager, an Orca broker, and
    89an Orca site authority within the same Java virtual machine that communicate using local procedure calls.
     10[[BR]]
    911The Orca actor servers run on a gateway node connected to both the public Internet (otg.cs.umass.edu) and the
    1012sensor node on the roof of the UMass-Amherst CS department. The sensor node on the UMass-Amherst roof, in
    … …  
    1315of the Xen virtual machine monitor and an instance of an Orca node agent. The Orca site authority communicates
    1416with the Orca node agent to instantiates virtual machines for experiments.
     17[[BR]]
    1518Each node is primed with the software necessary to create Xen virtual machines and sliver their resources. The
    1619local storage is a 32gb flash drive partitioned using logical volume manager. The Orca node agent snapshots a
    1720template virtual machine image pre-loaded on each node to create each experiment virtual machine. Additionally,
    1821tc is installed on each node to shape and limit each experiment’s network traffic.
     22[[BR]]
    1923Using the default Orca web portal, users are able to login and request slices on the ViSE testbed. Currently,
    2024only the sensor node on the CS roof is accessible by end-users. We have decided to wait until the end of winter to
    2125install the Orca node agent software on the two other ViSE nodes, since they are difficult to access in the winter.
    2226We expect to access them in early-to-mid April depending on the weather and the snow melt.
     27[[BR]]
    2328In addition to the software to support Orca, each node has the appropriate foundation software/drivers to
    2429operate the sensors, wireless and wired NICs, an attached Gumstix Linux embedded control node, and a GPRS
    … …  
    2934Operations and Management. We have documented the process to create compliant Domain-0 and Domain-U
    3035images at http://vise.cs.umass.edu.
     36[[BR]]
    3137The milestone is a pre-cursor to our sensor virtualization work. While users are able to create slices composed
    3238of Xen virtual machines bound to slivers of CPU, memory, bandwidth, and local storage, they are not able to access
