CDR File Storage
GTPP performs the CDR file storage in the following way:
-
When all the CGFs are inactive, all the CDRs are written into a file in HDD on the active GTTP endpoint.
-
The CDRs are stored on the standby GTPP endpoint.
-
After the inactive CGF becomes active, the CDRs are read from the file on the active GTPP endpoint and sent to the CGF.
-
After all the CDRs are read from one file, the file gets deleted from the active GTPP endpoint. Then, the file delete replication information is sent to the standby GTPP endpoint.
-
Standby GTPP endpoint deletes the file from HDD.
Note | During the CDR reading from HDD process, when some CDRs are sent to CGF and some CDRs are still in the file and the active GTPP endpoint becomes inactive, then the last read file is sent from the new active GTPP endpoint pod. The CGF receives various duplicate CDRs in such a case. |
