Restrictions for Configuring IPDR Streaming Protocol

Restrictions for Configuring IPDR Streaming Protocol
• An IPDR exporter can be connected to many collectors, but it will only send data to the highest priority
• Each IPDR session can be associated to one active (zero) or more standby collector with priority.

Information About IPDR Streaming Protocol

IPDR Streaming Protocol is designed to address the need for a reliable, fast, efficient, and flexible export
process of high volume data records such as billing, performance and diagnostic data.
The IPDR/SP process communicates with IPDR collectors. The IPDR streaming protocol supports multiple
IPDR sessions. The architecture supports primary and secondary collectors for failover purposes. At any time,
data is sent to only one collector. If the exporter to primary collector connection fails due to any reason, the
data is sent to the secondary collector. Depending on the network configuration, you can have only one primary
collector for each session, while for different sessions, you can have different primary collectors. For example,
there may be a billing collector, a diagnostic collector, and so on.
IPDR exporter refers to the Cable Modem Termination System (CMTS) and the IPDR collector refers to
Note
the network equipment.

Data Collection Methodologies

IPDR is the data generated or collected for various performance related metrics such as billing information,
diagnostics, network topology, signal quality monitoring, and other management data. These data are based
on the FCAPS model (Fault, Configuration, Accounting, Performance and Security.)
The IPDR client application communicates with the IPDR exporter using the IPDR_GET_SESSIONS message
to identify the streams provided by the exporter, and the exporter sends responses to the client using the
IPDR_GET_SESSIONS_RESPONSE message. This data collection method is based on the Operations
Support System Interface Specification (CM-SP-OSSIv3.0-I13-101008).
The IPDR_GET_SESSIONS_RESPONSE message includes the SessionBlock.reserved attribute to identify
the IPDR session ID. This attribute helps the Cisco CMTS router define an IPDR session ID for each data
collection mechanism supported for each IPDR service definition. This attribute was not used in Cisco IOS
Releases earlier to Cisco IOS Release 12.2(33)SCE.
The IPDR feature defines methods for the collectors or network elements to collect data from the CMTS.
Below is the list of collection methodologies:
Time Interval Session: In this method, the CMTS follows a schedule-based session to stream data at a periodic
time interval. A time interval is the time gap between two adjacent sessions' start messages. This method is
managed by the CMTS in controlling the start and stop operation of a session. The time interval session
terminates after the CMTS exports the records.
