First introduced.

21.18.15

Feature Changes

Previous Behavior: Each EDR, CDR, or UDR file is pushed to an external storage server through a single SFTP session.

In certain scenarios, it is possible for the file generation rate during busy hours to out-pace the push rate. This results in the development of a backlog that increases in /hd-raid/ local storage utilization.

New Behavior: In the StarOS 21.18.15 release, new push-count keyword is added to the EDR Module Configuration Mode, UDR Module Configuration Mode, and GTPP Server Group Configuration Mode. The push-count keyword allows users to send higher quantities of files during a single SFTP session. Higher push-count values can significantly increase the rate at which files are pushed to the external storage server in a single session.

Customer Impact: Pushing more files through a single SFTP session reduces the overall number of SFTP sessions required thus saving the time it would take to establish those sessions. This is especially useful in networks where it takes significant time (For example, 1-2 seconds) to establish individual SFTP sessions.

Command Changes

The push-count keyword has been added to several commands to set the number of EDR/CDR/UDR files that are transferred to the external storage server during a single SFTP connection. 

configure 
   context context_name 
      edr-module active-charging-service  
         cdr push-count push_count 
         default cdr push-count 
         exit

The push-count keyword has been added to UDR Module Configuration mode command: 

configure 
   context context_name 
      udr-module active-charging-service  
         cdr push-count push_count 
         default cdr push-count 
         exit

Notes:

  • push-count push_count : Specifies the number of EDR/CDR/UDR files transferred in each EDR/UDR push SFTP session. Default value is "1". push_count is configured as an integer value between 1 and 32, inclusive.


    Important
    When push_count is set to “1”, file transfer operation is functionally identical to legacy behavior.

The push-count keyword has been added to GTPP Server Configuration mode command: 

configure 
   context context_name 
      gtpp group group_name 
         gtpp storage-server local file push-count push_count  
         no gtpp storage-server local file push-count 
         exit

Notes:

  • push-count push_count : Specifies the number of EDR/CDR/UDR files transferred to remote system in each push to SFTP session. Default value is "1". push_count is configured as an integer value between 1 and 32, inclusive.


    Important
    When push_count is set to “1”, file transfer operation is functionally identical to legacy behavior.

  • no : Disables the push-count functionality.
