A device can identify video data included in network packets. For example, the device can identify a flow of network packets, the flow including uplink packets downlink packets. The device can determine that the flow includes at least one application data unit (ADU), each ADU including an uplink packet and multiple downlink packets. The device can determine that the at least one ADU includes video data based on determining that a throughput of the at least one ADU meets a throughput threshold, a an average payload size of the downlink packets included in the at least one ADU meets a size threshold, and a count of ADUs included in the at least one ADU meets a count threshold. Based on the at least one ADU including the video data, the device can perform an action.

Identifying video data included in network packets

A device may determine a subscriber identifier associated with a subscriber device. The device may obtain a service indicator based on the subscriber identifier. The service indicator may identify a network service to which a subscriber, associated with the subscriber identifier, is subscribed. The device may obtain a charging data function (CDF) identifier based on the service indicator. The CDF identifier may identify a destination CDF for charging messages associated with the network service. The device may establish a communication session associated with the subscriber device and the network service. The device may transmit one or more charging messages, associated with the communication session, to the destination CDF identified by the CDF identifier.
