Chapter 1 Service Selection Gateway Overview
SSG Architecture Model
In Figure 1-2, subscribers access the SESM web portal application using any web browser on a variety
of devices (such as a desktop computer over DSL). The Cisco 10000 series router (the SSG node)
forwards unauthenticated SSG traffic from the subscriber to SESM, configured as the captive portal and
default network. The SSG feature set of the router allows the service provider to design a service
selection access network.
As the gateway to service selection, subscribers can use SESM to manager their accounts, subscribe to
new services, and select those services that they want to use. Service providers can use SESM to offer
and advertise value-added services and to associate these services with their brand identities.
