Abstract
A computational system determines that a joining node in the federation infrastructure desires to join an identified subfederation within the federation infrastructure. The system accesses the joining node's group table, where the group table includes membership information identifying subfederations within the federation infrastructure. Each node in the federation maintains neighborhood information for each subfederation of which the node is aware. The system determines that no entry for the identified subfederation exists in the joining node's group table and, based on the determination, routes a group join message to a rendezvous point within the federation infrastructure. The rendezvous point checks its group table for an entry corresponding to the identified subfederation. The system also receives an indication from the rendezvous point indicating that the rendezvous point's group table does not include a corresponding entry for the identified subfederation and that the joining node is the first member of the identified subfederation.
