Name	Type	Description
TrafficFlowFilter	simple module	This module maps IP 4-Tuples to Traffic Flow Template (TFT) identifiers, which are used by the GtpUser module contained in the same node. It interacts with the Binder(1,2) to determine the destination of the packet. This module resides in any module that also includes a GtpUser module, such as eNodeB, gNodeB, PgwStandard, Upf, and MECHost modules. For instance, in a Upf module acting as the entry point of the 5G network, it identifies the destination endpoint of the GTP tunnel that the packet should traverse, which is the gNodeB serving the destination User Equipment (UE).
