8.1.
Duplicate CDR Detection
When AAA proxy is configured to write CDRs into the SMC hard disk, there are chances of
duplicate records being written to the file if the AAA proxy crashes after writing the file to
the RAM disk and before sending an ACK to AAAMgr. To prevent this, a mechanism is
now in place for the AAA proxy to avoid writing duplicate records when AAAMgr
retransmits the request later.

Intelligent Packet Monitoring System (IPMS)
The Starent Networks now provides IPMS (Intelligent Packet Monitoring System) solution
for operators to analyze and investigate call related events on the Starent Networks Access
Gateways (AGWs) like PDIF, PDSN, GGSN, SGSN, etc.

Gateways (AGWs) like PDIF, PDSN, GGSN, SGSN, etc.
The Intelligent Packet Monitoring System application provides the functions to assist
operators to analyze and investigate call related events at a later point of time. When IPMS
is enabled for a product, the AGW sends a copy of call control events as well as system
event packets (IKE, Proxy-MIP, RADIUS, DIAMETER etc.) with some additional
information to an external server for every call as part of normal system processing. The
external server stores the received call control events and system event packets for later
analysis.
