Usage-Based Billing and DOCSIS Support on the Cisco CMTS Routers
The usage-based billing feature supports these DOCSIS features on the Cisco CMTS routers:
•
DOCSIS 1.0, DOCSIS 2.0, and DOCSIS 3.0 compliant cable modems are supported.
•
Best Effort service flows are supported for DOCSIS-compliant cable modems.
•
Secondary service flows are supported for DOCSIS-compliant cable modems.
•
Dynamic service flows are supported for DOCSIS-compliant cable modems.
•
Information about deleted service flows is available only for DOCSIS 1.1 service flows but not for
DOCSIS 1.0 service flows.
•
Support for terminated service flows must be enabled using the cable sflog command in global mode.
Standards
The Usage-based Billing feature is based on several open standards, allowing it to be supported by a wide
range of commercial and custom-written billing applications. The following standards provide the major
guidelines for writing and using the billing records that the CMTS produces:
• Extensible Markup Language (XML)—A metalanguage that in turn can easily define other markup
languages to contain any kind of structured information, such as billing records. An XML-based approach
allows the collected billing information to be used by and distributed among many different billing
applications from different vendors. It also allows the format to be easily updated and customized to
meet the needs of different providers.
• IP Detail Record (IPDR)—An open, vendor-independent standard, defined in the Network Data
Management—Usage (NDM-U) For IP-Based Services specification, to simplify billing and usage
record-keeping for any type of services that can be delivered over an IP-based network. Service providers
can use IPDR to create unified billing applications for all of their services, such as DOCSIS or
Voice-over-IP, even though those services use different protocols and application servers.
• DOCSIS Operations Support System Interface (OSSI) specification—A DOCSIS specification that
defines the requirements for the network management of a DOCSIS network, including a Subscriber
Account Management Interface Specification (SAMIS) for a billing record interface. The DOCSIS 2.0
version of this specification states that a CMTS is not required to provide a billing interface, but if the
CMTS does provide a billing interface, it must be based on the IPDR/XML standards.
For further information about these standards, see the documents listed in the “Standards” section on page
38 .
Tip
IPDR Service Definition Schemas
To standardize the management of objects, service definition schemas are associated with IPDR just as MIBs
are associated to SNMP.
