GTPP Changes in Release 17
▀ GTPP Enhancements for 17.0
▄ Release Change Reference, StarOS Release 17
202
New Behavior: Even for a default configuration of
accounting-mode
under APN, this will be indicated in “
show
configuration
” both in verbose and non-verbose modes.
CSCum59328 - GTPP requests should be sent to any available CGF server in a
group
Applicable Products: GGSN, P-GW, SGSN, S-GW
Feature Changes
Load Balancing of CGF Servers
It has been verified that the gateway performs load balancing of the CDRs across all the available CGF servers. CDRs
for a given session can be sent to any available CGFs. If one CGF goes down, the CDRs are distributed to all other
available CGFs.

Feature Changes
Redesign of CDR Module
Previous Behavior:
Dictionary-specific checks were present all over the code. For any new feature enhancements or incremental
changes, code-changes were time-consuming and error-prone.
The default GTPP dictionary is starent.
In release 16.0, a new flexible and extensible framework was implemented to generate eGCDR and PGW-CDRs.
Customer had to use “
gtpp egcdr new-path
” CLI command to use the new CDR framework.
New Behavior:
This new framework has been extended to define a GTPP dictionary in a structured format using a “Dictionary
Definition Language (DDL)”. Using this language, customers can clearly define fields, triggers and behaviors
applicable for a particular GTPP dictionary.
applicable for a particular GTPP dictionary.
DDL text file will be parsed at compilation time and metadata will be populated to generate eGCDR and PGW-
CDR. This metadata makes the new framework more modular and maintainable. This will help in faster
turnaround time in supporting any new enhancements.

turnaround time in supporting any new enhancements.
Customers should explicitly configure the dictionary as there will be no default dictionary. If no dictionary is
configured, then eGCDR/PGW-CDR will not be generated.
