Stitching Service Details

The GENI SCS was developed by MAX and provides path information to applications that create slivers between GENI sites. The service also track VLAN delegation for all GENI sites that support stitching. For a list of VLANs delegated by all aggregates supporting stitching see the Delegated GENI Stitching VLANs page. Also any GENI aggregate that supports stitching provides information details in its GENI aggregate page details.

Stitching Connections to GENI End-points

Using GENI credentials, or credentials from an InCommon identity provider, users can request GENI resources using any tools that supports stitching, such as (GCF stitcher, GENI Portal jFed or Jacks tools, and via jFed at iMinds. Production GENI sites that support stitching and are known to the GENI SCS are documented in the GENI Network Stitching Sites page.

Stitching Path details

The GENI SCS supplies path and VLAN information for all sites listed at GENI Network Stitching Sites. Path chosen may include one or more of the following network aggregates: ION, AL2S, MAX, PG Utah (Utah IG sites only).

Path details are not captured here as they are continuously expanding.

Topology Information

For a list of known stitching aggregate refer to the the GENI Network Stitching Sites page or simply use the omni tool to get a list of known aggregates.

VLAN Translation

The SCS supports interactions with the ION, AL2S and MAX network aggregates, and all support VLAN translation.
