IP Identification (ID) Field

By default, non-fragmented UDP packets generated by media interfaces have the ID field set to 0. You can configure the Oracle Communications Session Border Controller to populate this field with an incrementing value by adding the increment-ip-id option in the media manager. Every non-fragmented packet sent will have its ID increased by one from the previous packet sent.

Using a packet trace application, egress packets from the Oracle Communications Session Border Controller will have an ID field that appears to be incrementing. Enabling the ID field can help distinguish a retransmitted non-fragmented application layer packet from a packet retransmitted by the network layer in monitoring or lab situations.
