Trafc Flow
Template
Trafc Flow Template (TFT) is to assign different priorities to different types of
trafc in order to optimize performance.
When more than one type of trafc is needed, you must use both a primary and
a secondary prole. For the BGAN core network and the terminal to classify
packets received from the external network into the proper prole, you need a
trafc ow lter.
When using a secondary prole, assign that the system transmits/receives by
ltering trafc for specic addresses, protocols, and ports.
