VirginiaTech Stitching Confirmation Tests

This pages capture the detailed test logs for each test defined in the New Site Stitching Confirmation Tests page. For the sites status see the New Site Stitching Confirmation Tests Status page.

IG-ST-1 New Site to GPO IG topology

The VirginiaTech site advertises the following stitching details:

Experimenter may not need any of this data, but it is helpful to reference when trying to determine how many VLANs are delegated for stitching at the site or how much bandwidth can be requested.

IG-ST-5 Site Information

Various pages include stitching information for a site. Each of the following were verified for this site:

  1. Verified that stitching VLANs and Device URN information exists in the VirginiaTech Aggregate page.

  1. Verified that Delegated GENI Stitching VLANs for site are documented at the Delegated GENI Stitching VLANs.
  1. Stitching Computation Service logs were reviewed while testing stitching to this site, no issues found.
  1. Added site to the list of GENI Network Stitching Sites.
