Chapter: IPDR Streaming Protocol

IPDR Streaming Protocol

The Cisco cBR Series Converged Broadband Routersupports the Internet Protocol Detail Record (IPDR) streaming protocol feature that provides high volume data exported from the network equipment to mediation systems such as the Operations Support Systems (OSS) or Business Support Systems (BSS). IPDR provides information about IP-based service usage and other activities that are used by OSS and BSS. This protocol provides a mechanism to collect data from various network elements or equipment using a push model as opposed to the conventional Simple Network Management Protocol (SNMP) polling mechanism.

Based on the DOCSIS 3.0 specifications, the IPDR feature optimizes time and resource efficiency in the transfer of large amounts of performance metrics to the management systems. DOCSIS 3.0 introduces five management features or the FCAPS model. FCAPS represents Fault, Configuration, Accounting, Performance and Security.

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 operating collector at any given time.
  • 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.


Note
IPDR exporter refers to the Cable Modem Termination System (CMTS) and the IPDR collector refers to 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.


Note
During the course of a one-time interval when the CMTS is streaming records, if another time interval is expected, the CMTS will ignore the new time interval and continue exporting the data until the previous time interval ends.

Event-based Session: In this method, the CMTS can export records at any time, when the session is open. In other words, this method works on an open-ended session.

Ad-hoc Session: In this method, the CMTS creates a session, allows data streaming, and closes the session when the data export is complete or when a closing command is generated.

A new session is created by issuing the ipdr session command. After, the CMTS receives the FLOW_START message from the collector, the CMTS exporter sends a SESSION_START message to start exporting the IPDR data from the collector. After all data is transported, the exporter receives a ACK message from the collector, and then sends a SESSION_STOP message to the collector. This method is known as the Ad-hoc session.

How to Configure IPDR Streaming Protocol

This section describes the configuration tasks that are performed when using the IPDR streaming protocol feature on the Cisco CMTS platforms.


Note
Use no ipdr command to remove the IPDR configuration.

Configuring the IPDR Session

To enable the CMTS application to add a session to the IPDR exporter, use the ipdr session command in global configuration mode.

Use the no form of the command to remove the IPDR session.


Note
  • The session ID must be unique.
  • To remove an active session, you must deactivate it before removing it.

            Adds an IPDR template to the IPDR session.

             

            Configuring the IPDR Exporter

            IPDR exporter parameters such as keepalive timer count, the maximum number of unacknowledged records, and unacknowledged timeout interval value can be configured using the following commands.

            • ipdr exporter keepalive—Sets the keepalive timer count value on the IPDR Exporter.
            • ipdr exporter max-unacked—Sets the maximum number of unacknowledged records on the IPDR Exporter.
            • ipdr exporter ack-timeout—Sets the time interval for acknowledged records on the IPDR Exporter.

            Note
            The default value for DataAckTimeInterval is 60 seconds and the default value for DataAckSequenceInterval is 200 seconds.

            You can set the values for the IPDR parameters to customize exporter for the collectors used in the facility. However, these commands are optional, so if not configured, the default values of the commands are used when ipdr exporter start command is executed.

            Procedure
               Command or ActionPurpose

              Verifying IPDR Streaming Protocol

              This section describes the commands used for verification of the IPDR streaming protocol feature on the Cisco CMTS platforms.

              Verifying the IPDR Collector

              The show ipdr collector command displays the collector information, message statistics, and event for all the sessions that are associated with the collector.

              The following example shows the sample output for the show ipdr collector command. 

              Router# show ipdr collector federal
Collector Name: federal, IP: 192.0.2.0, Port: 0
2001-07-05T19:28:22 Collector in session 1 Statistics:
 Transmitted 12658 Acknowledged 12658 Enqueued 12658 Lost 0
 Last Event: Event Id 1 IPDR_EVENT_SERVER_CONNECTED - INCOMING
Router(config)#

              Verifying IPDR exporter

              The show ipdr exporter command displays information about the IPDR Exporter state as listed below.

              • started
              • not started
              • not initialized

              The following example shows the sample output for the show ipdr exporter command: 

              Router# show ipdr exporter 
IPDR exporter is started.
Current parameters:
        KeepAliveInterval   :300
        AckTimeInterval     :60
        AckSequenceInterval :200
Router#

              Verifying IPDR session

              The show ipdr session command displays the session details such as the session ID, description, and the session state for all sessions as well as for a specific session.

              The following example shows the sample output for the all keyword for the show ipdr session command. 

              Router# show ipdr session all
Session ID: 1, Name: utilsta, Descr: test, Started: False

              The following example shows the sample output for the session_id keyword for the show ipdr session command. 

              Router# show ipdr session 1
Session ID: 1, Name: utilsta, Descr: test, Started: False
2001-07-05T19:36:28 Statistics:
Transmitted 0 Acknowledged 0 Enqueued 0 Lost 0
queuedOutstanding 0 queuedUnacknowledged 0
1 Collectors in the session:
Name: federal, IPAddr: 192.0.2.0, Port: 0, Priority: 1

              Verifying IPDR Session Collector

              The show ipdr session collector command displays the details of a collector that is associated with a specific session. Because there can be multiple collectors associated to a session, this command is used to show a specific session-collector pair.

              The following example shows the sample output for the show ipdr session collector command. 

              Router# show ipdr session 1 collector federal 
Session ID: 1, Name: utilsta, Descr: test, Started: False
Collecotr Name: federal, IP: 192.0.2.0, Port: 0
2001-07-05T19:38:02 Collector in session 1 Statistics:
 Transmitted 0 Acknowledged 0 Enqueued 0 Lost 0
 Last Event: Event Id 0 WRONG_EVENT_ID

              Verifying IPDR Session Template

              The show ipdr session template command displays the list of all active templates supported by a specific session.

              The following example shows the sample output for the show ipdr session template command. 

              Router# show ipdr session 1 template 
Template ID: 2, Name: http://www.cablelabs.com/namespaces/DOCSIS/3.0/xsd/ipdr/DOCSIS-CMTS-CMSERVICE-FLOW-TYPE, Type: DOCSIS-Type, KeyNumber: 22
Session 1 has totally 1 templates.
