Adjacent Diameter Node (ADN) data measurements are reported to the DSC ADN file. All ADN Connections report to this file, including INTERNAL, DSC DB, UA, and XML ADNs.
The Ribbon Signaling System provides ADN data measurements, as shown in the example provided in the following figures.
Note
To view the comma-delimited data measurements file retrieved from the DSC, save the file using a .csv file extension (comma-separated variables file type) and import into a spreadsheet.

The Instance represents the object in the application that is generating the statistics and is a string with the format <a> <b> ADN <c> <d>, as follows:
<DSC Instance Name> <DSC Node Name> ADN <ADN Name> <Slot>
ADN names are based on configuration data. When an ADN name is modified, a new record (row) is created in the data measurements file.
In the preceding data measurements example, the Instance is defined as:
a : DSC Instance Name = DSC-Macketh
b : DSC Node Name = sport.satellite.com
c : ADN Name = dsc30.sat.ply.com
d : Slot = 12
Note
Data measurements for an active or inactive ADN connection may appear in the DSC ADN file as zero entries in all fields. An ADN connection which does not generate any ADN data measurement appears in the DSC ADN file with zero entries.
The DSC ADN data measurement fields are listed and described in the following table.
ADN Counters data measurement field listing and description
Name | Type | Description |
|---|---|---|
Request Received | Count | Request messages received on this ADN. |
Requests Sent | Count | Request messages sent to this ADN (Request flag set in the diameter header). Note that messages received and messages sent should be the same in almost all cases, since message discards are quite rare (an error message is still a message). |
Answers Received | Count | Answer messages with the error bit cleared (successful answers), or redirect answers (error bit set and result code set to redirect) received on this ADN. A difference between requests sent and answers received indicates either requests in transit or transactions that do not complete successfully. |
Answers Sent | Count | Answers sent to this ADN. |
Errors Received | Count | Error answers other than redirects. |
Redirects Received | Count | Redirects received on this ADN. |
Messages Received | Count | Messages received on this ADN. |
Messages Sent | Count | Messages sent to this ADN. |
Bytes Received | Count | Bytes received on this ADN |
Bytes Sent | Count | Bytes sent to this ADN. |
Average Transmit Queue Time | Average | The average amount of time the message spends in the application level transmit queue, until it is sent to the transport layer. At most one message is sampled on a timer expiry. |
Transmit Queue Time Sampled Messages | Count | Number of messages sampled for the Average Transmit Queue Time. |
Average Transaction Time | Average | The time in milliseconds between when a request is received and the corresponding answer is received. This event is not counted for DSC INTERNAL ADNs.
|
Transaction Time Sampled Messages | Count | Number of messages sampled for Average Transaction Time. |
Average Transmit Queue Depth | Average | Average number of messages in the transmit queue (sampled on a timer). Recall that the transmit queue contains request and answer messages that are waiting to be sent on the network. |
Transmit Queue Depth Sample Size | Count | Number of messages sampled for Average Transmit Queue Depth. |
| SCTP Retransmission Data Chunks | Count | Number of SCTP data chunks retransmitted on this ADN with SCTP association. |
| Realm Redirects Received | Count | Number of Diameter answers with the error bit set and the Result-Code set to DIAMETER_REALM_REDIRECT_INDICATION (3011) received on this ADN.
