One-to-many synchronization

The one-to-many pattern involves one replica, or root site sending packets to all other replicas in the family.

In the hub patterns (Figure 1 and Figure 2), the hub replicas exchange packets with all spoke replicas. In the tree pattern (Figure 3), the root replicas exchange packets with branch replicas.
