GENI Network Stitching Sites

Last update: 2013-12-02

The following sites have been tested and are available for GENI Network Stitching experiments:

  • GPO ExoGENI
  • GPO InstaGENI
  • Mid-Atlantic Crossroads (MAX) InstaGENI
  • NYSERNet InstaGENI
  • University of Kentucky ProtoGENI
  • University of Missouri InstaGENI
  • University of Utah Downtown Data Center InstaGENI
  • University of Utah InstaGENI
  • University of Utah ProtoGENI
  • University of Wisconsin

For an example experiment that uses GENI Network Stitching feature see this GENI Network Stitching Example page.

Notes:

  • GENI Network Stitching is actively being developed and tested, which may make the Network Stitching feature unreliable for experiments.
  • Various stitching scenarios have been tested, and example request RSpecs from testing can be found at this location.
  • To run stitching scenarios without the ExoSM for the GPO ExoGENI rack use the stitcher option --noExoSM. If this option is not specified, than the request is submitted to the ExoSM aggregate.

Stitching Topologies

As of 2013-12-02, the site combinations in the following matrix have been tested with the GCF tool named stitcher.py. If you are interested in the RSpec used, click on the check mark to view the request RSpec used for testing:

gpo-ig

Note: All existing compute resource (raw-pc, openVZ, Xen) are supported in stitched slivers.

The following are sample RSpecs for stitching sites added after 2013-12-06:

Site Name Sample Stitching RSpecs Site Name Sample Stitching RSpecs
MAX here University of Wisconsin here

Other topologies have been also tested and those RSpecs are provided here as examples that can be referenced and modified to used other sites:

Topology Description Sites in topology RSpec
Three nodes linear GPO IG <-> Utah PG <-> Utah IG stitch-3linear.rspec
Triangle topology Utah PG<->UKY PG<-> GPO IG <-> Utah PG stitch-triangle.rspec
Star topology Center=UtahDDC IG; Outer=UKY PG, Utah PG, Utah IG, GPO IG stitch-star-ddc.rspec

To modify any of these RSpecs examples simply do the following:

  1. In the node definition replace the URN for the component_manager_id with the URN for your site.
  2. In the link definition replace the name of the component_manager with the URN for your site.
  3. Modify all instance of the client_id and source_id or dest_id to be descriptive for your site.
