Overview

For information on which JUNOS routing platforms and releases a particular SDX release supports, refer to the SDX Release Notes.

The SAE interacts with a JUNOS software process, referred to as the SDX software process in this documentation, on the JUNOS routing platform. The SAE and the SDX software process communicate using the Blocks Extensible Exchange Protocol (BEEP).

When the SDX software process establishes a BEEP session for the SAE, the SAE configures an interface the JUNOS routing platform. The SAE builds the configuration for an interface using the policies stored in the directory. If the policies are subsequently modified, the SAE builds a new configuration, and reconfigures the interface on the JUNOS routing platform.The JUNOS routing platform stores data about interfaces and services that the SAE manages in one configuration group, and data about subscriber sessions, service sessions, and interface sessions in another configuration group.
