Service Manager Overview
The JUNOSe Service Manager application provides
authentication, service selection, and service activation and deactivation
to subscribers. The application also collects accounting information
and statistics, and monitors subscriber and service sessions.
Service Manager supports two client types—RADIUS
and CLI. Service Manager starts when it receives a request from a
RADIUS or CLI client. For RADIUS clients, RADIUS Access-Accept messages
and Change-of-Authorization-Request (CoA-Request) messages can create
and delete Service Manager subscriber sessions and activate and deactivate
service sessions. For CLI clients, CLI commands create and delete
the subscriber sessions and activate and deactivate service sessions.
A subscriber’s service is based on a service
definition — service definitions can include profiles, policies,
and quality of service (QoS) settings that define the scope of a service
granted to the subscriber. Service definitions can also specify statistics
configurations.
Service Manager provides convenience and flexibility
to both service providers and subscribers.
- Providers are able to separate services and access technology
and also to eliminate unprofitable flat-rate billing. They gain the
ability to efficiently design, manage, and deliver services that subscribers
want, and then bill subscribers based on connect time, bandwidth,
and the actual service used.
- Subscribers benefit by gaining access to multiple simultaneous
services—subscribers can dynamically connect to and disconnect
from the services, when they want and for how long they want. They
are billed based on the service type and usage, rather than being
charged a set rate regardless of usage.
