Nested Realms
Nested Realms is a Oracle Communications Session Border Controller feature that supports hierarchical realm groups. One or more realms may be nested within higher order realms. Realms and sub-realms may be created for media and bandwidth management purposes. This feature supports:
- Separation of signaling & media on unique network interfaces
 - Signaling channel aggregation for Hosted IP Services applications
 - Configuration scalability
 - Per-realm media scalability beyond single phy-interface capacity
 - Nested bandwidth admission control policies
