Sponsored by the National Science Foundation 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 ( has wide adoption in research and education networkswww.perfsonar.net –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

Sponsored by the National Science Foundation 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

Sponsored by the National Science Foundation 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

Sponsored by the National Science Foundation 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
