Overview of the ASG
The ASG allows a gateway client—an application that is not part of the SDX network—to interact with SDX components through a Simple Object Access Protocol (SOAP) interface. This feature is useful for business-to-business (B2B) situations, such as wholesaler-retailer environments. Typically, the wholesaler owns and administers the SDX components, whereas the retailer maintains a database of subscribers. Retailers purchase services from one or more wholesalers and sell the services to their subscribers.
The ASG supports Web applications that allow gateway clients to interact with the SDX network. The SDX owner installs, configures, and administers the Web applications. Using information provided by the SDX owner, the business partner creates gateway clients to communicate with the SDX components.
The ASG offers the following Web applications:
- The Dynamic Service Activation Web application (subsequently known as Dynamic Service Activator) allows a gateway client to dynamically activate and deactivate SDX services for subscribers and to run scripts that manage the SAE. For more information about this application, see Chapter 3, Activating Services Through SOAP.
- The Subscriber Management Web application (subsequently called Subscriber Manager) allows a gateway client to create and modify subscriber data and to manipulate the workflow application. For more information about this application, see Chapter 4, Managing Subscribers Through SOAP.
Figure 1 shows the architecture for the ASG.
The application library also provides the Juniper Networks Intrusion Detection and Prevention (IDP) E-Mailer application as a gateway application that uses the gateway extension to map subscriber IP addresses to e-mail addresses and send e-mail to subscribers. For information about this application, see Chapter 10, Sending E-Mail to Subscribers.
