Global ADOM layer
The global ADOM layer contains the following key pieces:
- The global object database
- All header and footer policies
Header and footer policies are used to envelop policies within each individual ADOM. These are typically invisible to users and devices in the ADOM layer. An example of where this would be used is in a carrier environment, where the carrier would allow customer traffic to pass through their network but would not allow the customer to have access to the carrier’s network assets.
