The SRC software supports four types of services:
Use aggregate and infrastructure services together to apply policies across JUNOSe routers and JUNOS routing platforms, and other systems that have a supported device driver.
Use script services to create customized service implementations, such as a service to configure firewall policies on a device that does not have a supported device driver—for example, a Juniper Networks NetScreen-5GT appliance.
You can configure a permanent service—a service that the SAE automatically activates when it starts a subscriber session for subscribers who use that service. A typical application of this feature is to automatically activate a particular video service for all subscribers associated with a particular retailer. You can allow subscribers to deactivate the service, or prohibit them from deactivating it, after the SAE has automatically activated it. To make a service permanent, set the permanent option in the service configuration.
