Service Selection Gateway

Cisco IOS Software-based SSG services provide subscriber authentication, service selection,

service connection, and accounting capabilities in conjunction with the Cisco CNS SESM, a

software toolkit that resides on a Windows, UNIX, or Linux server (Figure 3). Integrated services

routers with SSG services can support up to 1000 users and can provide an ideal system for large,

multiservice provider hotspots (for example, airports) and distributed public WLAN network

deployments:



SSG can authenticate and authorize subscribers to access public (or enterprise) WLAN

services.



In conjunction with a billing server, SSG can provide per-subscriber, per-service billing in

both post- and prepaid billing modes.



In conjunction with SESM, SSG can provide a Web portal for subscriber authentication and

self-subscription, as well as service provider branding.



SSG provides open-garden and walled-garden services for controlled access of information

to subscribers.
