Future of graphical resource assignment tools


GENI Experimenter PortalIntroduction

Resource Allocation Tools


Resource Allocation ToolsGENI Experimenter Portal

  • Uses GENI AM API to manage resources

    • Currently 7 aggregates (ExoGENI, InstaGENI, ProtoGENI)

  • Point-and-click web-based UI

    • Not particularly “graphical” or “visual”

  • Good introductory tool

    • Makes easy things easy, hard things possible

  • Capable of any web-based presentation

    • Topology visualization

    • RSpec construction (visual, textual)

    • Tool/portal integration or linking

  • Limited capabilites

    • No topology embedding; one aggregate at a time


Resource Allocation ToolsLooking ahead

  • There is room for many resource assignment tools

    • They fill different niches: beginners, advanced users, scriptable, adaptive

  • Innovation is important

    • Borrow ideas from others, let experimenters vote with their feet

  • Standards are key

    • Allow access to all aggregates from all tools

    • Construct/embed with one tool, view/modify with another


Integration of portals and all tools with graphical interfaces


Integration of Portals and Tools


Tool/Portal integrationGENI Experimenter Portal

  • The GENI Experimenter Portal currently integrates with existing tools in several ways

    • Embeds Flack

      • Download from Utah, pass in slice and user context

    • Provides configuration data package for omni

    • Acts as OpenID identity provider to Seattle

  • Preliminary discussions with GEMINI to support integration


Tool/Portal integrationLooking Forward

  • Common constructs for tool interoperability

    • Standardize naming, semantics on UIs

  • Focus on inputs/outputs of the various lifecycle phases

    • Encourage interoperability and an open marketplace

  • Tools should:

    • Use standard and common APIs (eg. GENI AM API)

    • Engage in good security practices (private keys, passwords)

    • Hosted tools need a “speaks for” capability


Tool/Portal integrationLooking Forward (cont.)

  • Pushing towards a seamless user experience while providing choice and an open marketplace

  • Tools will need more standard APIs (SA, MA/IdP)

  • Tools should choose an appropriate authentication model (certificates, OpenID)

  • Link to online tools, embed online apps, integrate with desktop tools

  • Consume and produce standard artifacts (RSpec)

  • Documentation!
