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
• 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

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

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. If you are interested in the RSpec used, click on the check mark to view the request RSpec used for testing:

	gpo-eg	gpo-ig	missouri-ig	nysernet-ig	uky-pg	utahddc-ig	utah-ig	utah-pg
gpo-eg	N/A	Soon	✔	✔	No	✔	✔	✔
gpo-ig	Soon	N/A	✔	✔	✔	✔	✔	✔
missouri-ig	✔	✔	N/A	✔	✔	✔	✔	✔
nysernet-ig	✔	✔	✔	N/A	✔	✔	✔	✔

utah-ig	✔	✔	✔	✔	✔	✔	N/A	✔
utah-pg	✔	✔	✔	✔	✔	✔	✔	N/A

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
3 node linear	GPO IG <-> Utah PG <-> Utah IG	​stitch-3linear.rspec
triangle topology	Utah PG<->UKY PG<-> GPO IG <-> Utah PG	​stitch-triangle.rspec
Start topology	Center=UtahDDC IG; Outer=UKY PG, Utah PG, Utah IG, GPO IG	​stitch-star-ddc.rspec

To modify any of these RSpecs simply:

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