GENI I&M Update:Sharing MD Objects with Researchers, MDA Service • Goals • Architecture Overview • Process • Functional Services • Measurement Data Flows/Transfers • Measurement Traffic Flows • Principal Use Cases • Types of Services • Control Framework Implications • Measurement Data Objects and Descriptors • Controlling Access to Measurement Data Objects • Current Status • Current I&M Design and Prototyping Efforts • I&M Service Deployments • References: • I&M work in progress: http://groups.geni.net/geni/wiki/GeniInstMeas • I&M capabilities catalog: http://groups.geni.net/geni/wiki/GENIIandMCAPCAT • I&M architecture document: http://groups.geni.net/geni/wiki/GeniInstrumentationandMeasurementsArchitecture • Available I&M tools: http://groups.geni.net/geni/wiki/GeniInstMeas#AvailableGENIIMTools
Use Case 4: Experimenter (or Operator) moving MD to an archive, with an option to share with other Researchers • An Experimenter (or Operator) can move MD Objects (directories or files) to (and from) a Type 2 User Workspace (UW) service • Always includes associated MD Object Descriptor (“metadata”) • Identifiers and annotation in Descriptors allow Experimenter (or Operator) to manage thousands of files gathered during an experiment, or when monitoring infrastructure • The Experimenter (or Operator) can move selected MD Objects (directories or files) from UWservice to the Type 4 Digital Object Archive (DOA) service, to become persistent Digital Objects • Digital Object receives a persistent global identifier • Digital Object includes an associated Descriptor • Descriptor includes sharing policy, that DOA service is obligated to follow
Type 4 I&M Service: With portal to share MD • Each Type 4 I&M service: • Has web portal to observe and share MD • Web portal authorization mechanism required to admit only specified users; should reuse accepted certificate/credential arrangements • Example: Presentation service that is part of Instrumentation Tools • Example: Digital Object Archive (DOA) service prototype from CNRI • DOA service required to follow sharing policy within Descriptor associated with a Digital Object
User Workspace Service • Each User Workspace (UW) service: • Is a Type 2 common service, assembled, configured and managed by a Service Provider in their sliver using Control Framework (CF) mechanisms • Service Provider offers UW slivers (e.g., Linux file systems) to Experimenters and Operators via CF mechanisms • UW service sliver is a resource to be obtained by an Operator via CF, and then configured and managed • Policy is required to make sliver available to selected experimenters and operators
Digital Object Archive (DOA) Service • Each DOA service: • Is a Type 4 service with a web portal to observe and share MD • Required to follow sharing policy within Descriptor when sharing Digital Object • Policy required to make digital object available to selected users within GENI, selected users outside of GENI, and/or all others
