New Site Stitching Confirmation Tests

Upon completion of the InstaGENI Confirmation Tests or ExoGENI Confirmation Tests for a new GENI Rack site, the GPO may also complete a series of GENI Network Stitching Confirmation Tests to validate supported stitching topologies for the site. These Stitching confirmation tests verify experimenter ability to stitch network resources and the the ability to monitor the topology when possible. All stitching experiments defined in this plan assume that Omni tools are used for all AM API operations. See the New Site Stitching Confirmation Tests Status page for details about sites that have been tested.

InstaGENI Stitching Test Topologies

The InstaGENI (IG) Stitching Tests (ST) verify some basic topologies that are common to all rack types, but it is expected that network access will vary across rack types. Therefore, a set of tests is defined for each rack type.

IG-ST-1 New Site to GPO IG topology

A stitching test between the new site and the GPO IG rack will be performed for each network path available at the new site. For example, if the site is connected to both ION and AL2S, two separate tests will be run to verify that both path can be requested and used between the two Xen VMs at each site. This is the ION topology that will be verified:

If the New IG site is connected to AL2s and the GPO IG is connected to ION, the following topology will be verified:

For each stitching path tested in this test case, performance data will be captured between the New IG Site and GPO IG for TCP, UDP and ping statistics.

IG-ST-2 New Site to GPO IG Loop topology

A stitching test between the new site and the GPO IG rack will be performed which uses two stitched links between the 2 sites sites using OpenVZ VMs:

IG-ST-3 New Site 3 node linear topology

A stitching test that will use the new site as part of a linear topology, where each rack reserves one host and traffic is exchanged between the end-points:

IG-ST-4 New Site to GPO EG interoperability

A stitching test between the new site and the GPO IG rack will be performed for each network path available at the new site. For each stitching path tested in this test case, performance data will be captured between the New IG Site and GPO IG for TCP, UDP and ping statistics.

If the New IG site is connected to AL2s and the GPO EG is connected to ION, the following topology will be verified:

IG-ST-5 Site Information

As part of the Site Stitching verification, the following will take place:

  • Verify new site have stitching VLAN and Device URN information in the InstaGENI Aggregate page.
  • Verification that Delegated GENI Stitching VLANs for site are documented here.
  • If possible, access Stitching Computation Service and review logs during each test case.
  • Upon completion add site to the list of GENI Network Stitching Sites.

ExoGENI Stitching Test Topologies

The ExoGENI (EG) Stitching Tests (ST) verify the same basic topologies that are verified for InstaGENI, but it is expected that network access will vary across rack types, therefore ExoGENI tests are defined for each rack type.
