     5Period: 3Q09
     6== I. Major accomplishments ==
     7
     8In the first year the following were the major project accomplishments:
     9  1. Extending OMF to support multiple heterogeneous testbeds
     10  1. Extending OMF with the support for mobile (potentially disconnected) experimental nodes
     11  1. Design of extended OMF interfaces to support WiMAX basestation aggregate manager
     12  1. Integration of support for wide area (L2) connectivity
     13
     14The project conducted demonstrations at all three GECs covering thesel 4 major
     15accomplishments.
     16  * GEC4: Demonstration of mobile/disconnected operation
     17  * GEC5: Demonstration of wide‐area heterogeneous testbed coordination
     18  * GEC6: Demonstration of WiMAX support
     19
     20The project has released an external website dedicated to OMF with publicly available
     21source code repository and wiki and mailing lists that are supporting a wide user
     22community. We also released two new major versions of OMF software (5.1 and 5.2)
     23with each version adding a subset of features corresponding to major accomplishments.
     24This website is located at: http://www.mytestbed.net/

     26== II. Description of work performed during last quarter ==
     27
     28=== A. Activities and findings ===
     29
     30'''Extending OMF to support multiple heterogeneous testbeds'''[[BR]]
     31Towards this goal, we have so far completed the following tasks: migration of all domain
     32specific configuration parameters to the Inventory database for that domain and
     33introduce support for different PC‐based hardware. We have also expanded the number
     34of supported platforms to include low power deployments as well as more powerful
     35(Quad Core) CPUs.
     36
     37Furthermore, we are currently working on modification of OMF communication to
     38follow publish‐subscribe paradigm.
     39
     40'''Supporting mobile nodes: local OMF/OML caching and distributing experiment scripts'''[[BR]]
     41The OMF was extended to support disconnected operation. The experiment script is
     42installed over (possibly wireless) control link in the vehicular node at the start of the
     43experiment. If this control connection becomes disconnected during the experiment,
     44the resource controller will continue to run governed by the time‐orchestrated
     45experiment script. We have refactored our measurement framework (OML v2) and
     46added temporary caching of collected measurement on disconnected nodes, and
     47automatic data retrieval upon reconnection.
     48
     49We have demonstrated these capabilities at GEC4 and GEC5.
     50
     51We have also started work on the year 2 milestone to support experimentation driven
     52by context, particularly by geographic location.
     53
     54'''Support for wide‐area (L2) connectivity'''[[BR]]
     55Early in the year, we worked with the NJEdge regional consortium to connect us to
     56regional center MAGPI East (Philadelphia). As part of this process, we acquired
     57dedicated fiber along the Route 1 corridor jointly with NJEdge. In the first half of the
     58year the section of missing fiber link between the Rutgers Food Science building and the
     59Route 1 fiber corridor (~1 mile) was installed and optical lambda service from NJEdge
     60was provisioned. This created 1Gbps optical link between our current location (Rt. 1
     61Technology Center, North Brunswick NJ) and carrier hotel (MagPI East) at 401 Broad
     62Street in Philly on the 9th floor. The ION connection was not provisioned due to missing
     63cross connect between I2 and MagPI. To avoid delays for other dependant deliverables,
     64we used L2 tunneling protocol (L2TP) over the excess capacity of 400Mbps on Rutgers
     65University's existing commodity feed to emulate expected L2 connectivity and
     66implement wide area networking. This link was used for a variety of testing scenarios,
     67including a single experiment with a mixture of individual resources on both ends of the
     68tunnel (with experiment coordination from both ends of the tunnel over multicast
     69traffic), running an aggregate manager for the resource on the opposite end of the
     70tunnel and measurement collection across endpoints.
     71
     72We have successfully conducted a GEC demo that utilised L2 wide area network link
     73from the New Jersey based ORBIT testbed to testbed facilities at NICTA in Sydney,
     74Australia.
     75
     76'''Integrating OMF with WIMAX Basestation'''[[BR]]
     77During the course of the first year, the WiMAX basestation was integrated into the
     78ORBIT network. This setup enables full accessibility of both the RF and ASN portions of
     79the basestation. In addition, we designed interfaces for two new OMF components: RF
     80Aggregate Manager (Gridservice) and ASN Aggregate Manager (Gridservice) that will
     81allow experimental end‐users to access the features of the WiMAX device and to control
     82basestation settings from OMF experiment scripts. We created a reference
     83implementation that allows access to RF parameters for each node that participates in
     84the experiment and allows creation of virtual machines on the ASN aggregate manager
     85(to support multiple simultaneous experiments).
     86
     87The GEC5 demonstration included preliminary integration with the Wimax project, by
     88showing a video transmission over a Wimax link within the vehicular experiment, GEC6
     89demonstration illustrated OMF interfaces to control basestation settings from OMF
     90experiment scripts.

     106=== D. Outreach activities ===
     107Number of minority/under‐represented students continues to be involved in the
     108project: Tripti Singh and Janani Chandrasekaran worked on mobility support while
     109Manasi Jagannatha worked on WiMAX integration. As part of WINLAB Summer
     110Internship we also had 6 undergraduate students using various elements of Orbit
     111testbed and working with OMF.
     112=== E. Collaborations ===
     113'''GENI Internal:''' During the first year, Cluster E framework group started a collaboration
     114with Brian Levine’s team from UMass with the objective of aligning control and
     115measurement interfaces for our mobile testbed. We also started collaborating with
     116Orca tema (Ilia Baldin) on more formalized resource description.
     117
     118'''External:''' In the first year, project was collaborating with two European program:
     119!OneLab and 4WARD. Also, OMF software is also being actively used in 15 testbeds
     120around the world.
     121
     122=== F. Other Contributions ===
     123We have also conducted a site visit with GPO in June and a demo of the current
     124framework to members of the GPO in November. We have also participated in
     125numerous panels at various GECs and participated in 3 workshops organized by the
     126GPO.
     127
     128We provided input for the GENI security architecture draft, provided examples of ORBIT
     129O&M data and our current data format in use, and are continuously supporting external
     130experimenters on the stationary ORBIT testbed.
