    3030=== Network Federation ===
    31 GENI is a federation of resources that are provided from different organizations. This makes network provisioning between sites challenging since there is no one organization that is responsible for provisioning the networking for a single slice. In the Internet we know very well how to achieve this and we have different federation protocols so that different network providers can peer and provide end-to-end connectivity to users. However, the GENI backbone provides Layer 2 connectivity between different organizations and Layer 2 peering is not as well explored in the Internet. To achieve this and to enable dynamic provisioning of networking connection per experiment, GENI has developed a mechanism called '''stitching''' that allows different organizations to provision parts of a Layer 2 link between two compute resources in a way that it guarantees end-to-end connectivity.
