Use-cases for GENI Instrumentation and Measurement Architecture Design

1. Use-cases for GENI Instrumentation and Measurement Architecture Design Team members: Paul Barford - University of Wisconsin – Madison Jim Griffioen - Univ Kentucky Prasad Calyam* - Ohio Supercomputer Center/OARnet Camilo Viecco - Indiana Univ Brian Hay – Univ Alaska *agreed to organize first writing and discussion July 22nd 2010

2. User Groups and Use Cases • Experiment Researchers • Have I got the resources I asked? • Is the experiment environment functioning as expected over my slice lifetime? • Can I trace my non-intuitive results to a problem in the environment? • Collect active and passive measurements at hop, link, path and slice levels… • I need processed measurements feedback to control my experiment progress… • Can I have an archive of the experiment measurements collected for offline analysis? • I would like to have sharing mechanisms to disseminate my experiment measurements… • Experiment (Opt-In) Users • Show me the end-to-end delay and loss characteristics of the network paths between my computer and all the P2P servers in the GENI experiment… • Show me whether I got all the resources (e.g., CPU, memory, disk space) with the performance that I expect in my virtual desktop computer… • Let me query the latest status of my application resources so that I can know the reason for the poor performance of my GENI experiment application… • Central (i.e., GMOC) Operators • I need processed measurements feedback of mis-behaving slices so that I can invoke “emergency shutdown” to swap them out! • Experimenter called GMOC about non-responsiveness of resources or unexpected behavior in a slice spanning multiple aggregates, notify status of user slice resources… • We want experiment meta-data after each slice expires to correlate infrastructure usage…

3. User Groups and Use Cases (2) • Aggregate Providers and Operators • Collect active and passive measurements at hop, link, path and slice levels… • Provide policies for measurement data acquisition/access to be granted based on the privileges assigned to the different user roles… • I need processed measurements feedback of mis-behaving slices so that I can swap the experiment out and/or reallocate resources… • GMOC has complained about non-responsiveness of resources or unexpected behavior in a slice using my aggregate, notify status of the user slice resources… • Archive Providers and Operators • Publish measurement archives in the repositories with suitable keywords that allow me to catalog indexes for future search and retrieval purposes… • Provide policies for measurement data acquisition/access to be granted based on the privileges assigned to the different user roles… • I would like users to use my tools and transformation libraries that deal with various data formats to: share, annotate, search and cite the measurement datasets in my repositories… • Researchers that use Archived Measurement Data • I would like to get search results and access to measurement archives when I use different search keywords… • I would like to be able to share (e.g., email, post on Twitter), annotate, search and cite the measurement datasets in repositories of several Archive Providers…
