Progress Report for the GENI Experiment Engine: GEC 20

Contract Deliverables

• Demonstrated real experiment using GEE at GEC-20

• Presented GEE at GEC 20 Experimenter Tools Session

• Demonstrated GENI-Wide File System at GEC-20

Technical Progress

• Integrated the GENIExperimentEngine slice with the VirtualTopologyService slice, conserving GENI physical machines and giving an avenue for programmable networking in future using GEE

• Brought the GEE Portal to production quality and integrated it with GENI's authentication service.

• Developed demonstration-quality network file system over Swift

• Brought up the Beanstalk messaging service and deployment commands to use it in a slicelet.

• Developed a live monitoring service for the GENIExperimentEngine ​http://www.lively-web.org/users/rick/GEEReport.html

• Developed and tested a reverse proxy to permit slices to offer location-based services over port 80.

• Removed a number of security holes in the portal.

• Expanded range of actions offered through the portal as planned in GEC 19 status

• The number of pre-allocated slicelets is now continually topped up, so there are always 10-20 available slicelets.

Ongoing Issues

• We remain highly reliant on GENI VLANs for the networking elements of the GENI Experiment Engine, and we need a guarantee that the VLANs that we allocate will be stable over, essentially, the lifetime of GENI -- at a minimum, we require some notice before a VLAN is torn down

• Need to continually renew the GEE slice on GENI, and reallocate slivers. The GEE, particularly the GEE Compute Engine, is designed as a set of long-running, stable services, not short-run experiments.

Outreach Activities

• GENI Experiment Engine presentation at GEC-20

• GENI Experiment Engine tutorial at US Ignite summit

Plans for GEC 20

• Bring filesystem and proxy to production-quality implementation

• Cleanup bug reporting and logging in the portal, and add alerts on errors, etc.

• Recruit a small number of experimenters to participate in GEE beta program

• Investigate design alternatives for GEE Slicelet hosts. We currently run in PlanetLab nodes, but could potentially do this in OpenVZ ProtoGENI images, and/or OpenCloud images
