Subscriber Management - Cisco SCE 8000 Installation And Configuration Manual

Chapter 1 Cisco Service Control Overview

Subscriber Management

Where the Cisco service control application for broadband (SCA BB) enforces policies on different
subscribers and tracks usage on an individual subscriber basis, the Cisco service control management
suite (SCMS) subscriber manager (SM) may be used as middleware software for bridging between OSS
and SCE platforms. Subscriber information is stored in the SM database and can be distributed between
multiple platforms according to actual subscriber placement.
The SM provides subscriber awareness by mapping network IDs to subscriber IDs. It can obtain
subscriber information using dedicated integration modules that integrate with AAA devices, such as
RADIUS or DHCP servers.
Subscriber information may be obtained in one of these ways:
•
•
Service Configuration Management
Service configuration management is the ability to configure the general service definitions of a service
control application. A service configuration file containing settings for traffic classification, accounting
and reporting, and control is created and applied to an SCE platform. The SCA BB application provides
tools to automate the distribution of these configuration files to SCE platforms. This standards-based
approach makes it easy to manage multiple devices in a large network.
Service Control provides a GUI to edit and create these files and a complete set of APIs to automate their
creation.
Data Collection
Data collection occurs as follows:
1.
2.
3.
RDRs contain a variety of information and statistics, depending on the configuration of the system.
Three main categories of RDRs include:
•
•
•
Push Mode—SM pushes subscriber information to the SCE platform automatically upon logon of a
subscriber.
Pull Mode—SM sends subscriber information to the SCE platform in response to a query from the
SCE platform.
All analysis and data processing functions of the SCE platform result in the generation of Raw Data
Records (RDRs), which the SCE platform forwards using a simple TCP-based protocol
(RDR-Protocol).
RDRs are processed by the Cisco service control management suite collection manager.
The collection manager software is an implementation of a collection system that receives RDRs
from one or more SCE platforms. It collects these records and processes them in one of its adapters.
Each adapter performs a specific action on the RDR.
Transaction RDRs—Records generated for each transaction, where a transaction is a single event
detected in network traffic. The identification of a transaction depends on the particular application
and protocol.
Subscriber Usage RDRs—Records generated per subscriber, describing the traffic generated by that
subscriber for a defined interval.
Link RDRs—Records generated per link, describing the traffic carried on the link for a defined
interval.
