Prioritizing a Source and Avoiding Duplicate Packets if Traffic is Received twice from Different Sources (Doc ID 1935406.1)

Goal

Prioritize a source of traffic over another one if there traffic monitored to OCOM/Palladion is overlapping partially  - for example if two OCSM probes, or an SBC and an OCSM probe are capturing/monitoring same traffic to OCOM/Palladion.

If the same traffic is received two or more times from different sources - from SBC via IPFIX (comm-monitor functionality of Oracle SBC) and a second time via the sniffing functionality of a OCOM/Palladion probe - this could result in duplicate packets. This could especially happen in scenarios where the SBC is supposed to monitor the traffic coming in from the public Internet and the traffic in the core network is monitored by the probe functionality.

Since the SBC monitors in every case the incoming side of a call, as well as the outgoing (so core and public are monitored), the core site might get monitored twice.
