  2. Project Summary • LAMP (Leveraging and Abstracting Measurements with perfSONAR) is an effort to use and extend the perfSONAR system for Instrumentation and Measurement (I&M) in ProtoGENI • perfSONAR (www.perfsonar.net) has wide adoption in research and education networks • One key to the success of perfSONAR system is its extensibility • Ability to wrap many data sources, while fully capturing relevant metadata • Key Goals of LAMP • Inclusion of various modes of operation • Slice creation with embedded I&M • Dynamic dedicated monitoring slice • Access to persistent I&M services • Generic metadata, including slice topology and data description to provide “lingua franca” for various I&M projects • Easy access to commonly-desired data • Easy support for experiment-specific metrics • Exploratory work toward GENI I&M Architecture 29-August-2010

  4. Accomplishments 1: Advancing GENI Spiral 2 Goals • One of the main Spiral 2 goals was to establish various Instrumentation and Measurement (I&M) Systems and to work toward a strawman proposal for a GENI-wide framework • LAMP has the twin goals of a working system and exploratory investigation toward the larger framework • The LAMP team has actively participated in the I&M WG to advance the I&M Architecture • This effort has been substantial and wasn’t reflected in our original milestones! • Development of an I&M System Prototype that integrates perfSONAR in ProtoGENI, while serving as a continuous experimenter • This helped improve the Control Framework by identifying needs of I&M systems, providing feedback on general CF use/design, and generating bug reports • We have paid substantial attention to Interoperability by understanding the various RSpecs used by CFs and looking toward a common representation • Similarly, we have faced Identity Management questions from the outset, and have worked toward support for this in LAMP 29-August-2010

  5. Accomplishments 2:Other Project Accomplishments • Deployed perfSONAR measurement infrastructure for ProtoGENI backbone nodes • Substantial integration with ProtoGENI • I&M infrastructure deployment and bootstrapping integrated with the CF • ProtoGENI AA support added to perfSONAR services and global infrastructure • ProtoGENIRSpec translated into UNIS topology schema • Developed a different approach for bootstrapping and configuring the perfSONAR I&M infrastructure that • Nodes configure themselves by retrieving annotations on the topology description of the slice • Continuous configuration changes possible • Nodes can push changes back into the topology description so that information is up-to-date (e.g. IP addresses) • The measurement and (UNIS) topology schema integration in the LAMP I&M system demonstrates a possible solution for storing and sharing measurement data from virtual topologies (i.e. non-public IP addresses, etc) 29-August-2010

  6. Issues • We (LAMP) need to improve in our completion (and revision if necessary) of project milestones • When we became substantially involved in the I&M WG, we let our own milestone languish as the analysis and description was largely the same • Lack of instrumentation/measurement resources (e.g. measurement boxes) at various aggregates • Creates difficulties in integrating substrate and slice measurement planes • Topology of the substrates should be described in more detail • Lack of dedicated measurement plane network • CFs and RSpecs are very different underneath • This will be a major barrier to fully integrating I&M systems to all CFs (i.e. bootstrapping, determining virtual topology vs physical topology mappings (including hostnames/IPs), etc). 29-August-2010

  7. Plans • Integrating the rest of the perfSONAR-PS services • Adapting the pS-PS-Toolkit web configuration tool for managing distributed services through changes to UNIS • Making the topology based (node) configuration service a full blown pS service • Improve GUIs available to GENI experimenters for visualizing perfSONAR data of slices (Periscope, perfAdmin, others) • Public release of software available to all experiments with documentation and user manual • Continued emphasis on GENI I&M Architecture document and discussion • The GPO is starting to formulate goals for Spiral 3. What are your thoughts regarding potential Spiral 3 work? • An increased emphasis on common language and more correspondence in RPecs. Diversity is good, but not for its own sake. 29-August-2010
