Netflow/IPFiX data model could be used to capture the data.

Stream doesn't generate the exact Netflow/IPFIX data; the best approximation you can do is to create aggregated tcp and/or udp streams that have src_ip, src_port, dest_ip, dest_port (+any other fields) as key fields and bytes_in/bytes_out/packets_in/packets_out as value fields. That will generate events with NetFlow-like stats. The limitations are: only tcp and udp transport protocols supported; not all netflow fields are supported, etc. so it may or may not work based on your use case.

As of version 7.0, Splunk Stream supports collecting Netflow, sFlow and IPFIX data directly
