Introduction
Cisco Broadband Access Center (BAC) automates the tasks of provisioning and managing customer premises equipment (CPE) in a broadband service provider network. The product provides a simple and easy way to deploy high-speed data, voice technology, and home networking devices.
BAC can be scaled to suit networks of virtually any size, even those deploying millions of devices. It also offers high availability, made possible by its distributed architecture with centralized management.
This release supports device provisioning by using the DSL Forum's CPE WAN Management Protocol (CWMP), as defined in the TR-069 specification, a standard for remote management of CPE. Additionally, BAC supports virtually any data models based on TR-069, TR-098, TR-104, and TR-106 extensions.
System Components
BAC comprises:
•A Regional Distribution Unit (RDU), which is software that you install on your server. The RDU is the primary server in a BAC deployment. Through its extensible architecture, the RDU supports the addition of new technologies and services.
•The Device Provisioning Engine (DPE), which is software that you install on your server. The DPE server handles all device interactions with the RDU.
•An administrator user interface through which you can monitor and manage BAC.
•A Java provisioning application programming interface (API), which you use to integrate BAC into an existing operations support-system environment. You can use the provisioning API to register devices in BAC, assign device configuration policies, execute CWMP operations on the device, and configure the entire BAC provisioning system.
System Requirements
You must have the Solaris 9 operating system installed on your system to use
the BAC software.Licensing Requirements
You require a valid license key to successfully provision devices that use BAC. These licenses are specific to the:
•CWMP technology
•DPE component
Note If you have not yet received your licenses, contact your Cisco representative.
New Features
The major feature of this release is BAC support for the CWMP technology.
This section briefly describes new or modified features found in the BAC 3.0 release:
CWMP Technology Support
This BAC release supports the CWMP technology, as defined in the TR-069 specification. CWMP details a mechanism that increases operator efficiency and reduces network-management problems through its capabilities, which include:
•Autoconfiguration
•Firmware management
•Status and performance monitoring
•Device diagnostics and troubleshooting
BAC supports devices based on the TR-069, TR-098, TR-104, and TR-106 standards. These devices include Ethernet and ADSL gateway devices, wireless gateways, VoIP ATAs, and other devices that are compliant with CWMP.
This release also provides for runtime-extensible data models to support any upcoming data-model standards or any vendor-specific data models.
Configuration Management
BAC vastly simplifies configuration management by including extensible templates for device configuration. BAC templates are XML documents that you can create in an easily readable format, and edit quickly and simply. The templates also provide flexibility of configuration options via a template-processing mechanism. You can use this mechanism to customize configurations for millions of devices from few templates.
Firmware Management
Firmware management in this release maintains and distributes sets of firmware image files to corresponding devices through the BAC system. An XML-based firmware rules template associates the firmware image files to groups of devices. BAC uses the rules in the associated firmware rules template to evaluate the firmware that is downloaded to the device.
Massive Scalability
BAC enhances scalability by partitioning CPE into provisioning groups; each provisioning group is responsible for only a subset of the CPE. A provisioning group is designed to be a logical (typically geographic) grouping of servers, usually consisting of one or more DPEs. A single provisioning group can handle the provisioning needs of up to 500,000 devices. As the number of devices grows past 500,000, you can add more provisioning groups to the deployment in BAC.
Standards-based Security
The CWMP security model provides basic security to accommodate less robust CPE implementations while allowing greater security for those that can support more advanced security mechanisms.
BAC provides device authentication based on:
•Shared secrets with the DPE by using Basic and Digest authentication.
•Device certificates. The two types of device certificates are:
–Generic—Certificate common to all CPE or a large subset of CPE.
–Unique—Certificate specific to a device.
BAC also provides a unique option of performing device-certificate authentication at a hardware load balancer and SSL accelerator, such as Cisco 11500 Content Services Switch.
Note BAC supports secure device provisioning by using SSL 3.0 and TLS 1.0.
Extensive Server Management
BAC provides extensive server-performance statistics, thereby enhancing capabilities for monitoring and troubleshooting. You can manage essential details such as server state, license information, communication between servers, and server-specific statistics by using the BAC SNMP agent or the various log files.
Device Diagnostics and Status Monitoring
This release provides device troubleshooting and diagnostics features that you use to focus on a single device and collect diagnostics information for further analysis.
By using this feature, you can query devices for any data, including:
•Configuration
•Live statistics
•Fault indications
•Log file
•Diagnostics results
BAC provides the following features to aid in troubleshooting devices:
•Device history—Provides a detailed history of significant events that occur in a device-provisioning lifecycle.
•Device faults—Detects devices with recurring faults, which can cause bottlenecks and affect network performance.
•Device troubleshooting—Provides detailed records of device interactions with BAC servers for a set of devices that are designated for such troubleshooting.
•Performance monitoring—Provides detailed performance statistics that are related to system performance across major components. It also provides an analysis of the statistical data to aid troubleshooting.
•Direct device operations—Executes operations such as IP Ping and Get Live Data on the device for more insight.
Easy Integration with Back-end Systems
This release provides easy integration with back-end system via BAC mechanisms, such as:
•The Java API, which you can use to perform all provisioning and management operations.
•The publishing extensions, which you can use to write RDU data into another database.
•The data export tool, with which you can write device information from the BAC system to a file.
•The SNMP agent, which simplifies integration for monitoring BAC.
•The DPE command line interface, which simplifies local configuration when you use it to copy and paste commands.
