Using a Traffic Flow Template

What is a Traffic Flow Template?
A Traffic Flow Template (TFT) is a packet filter list allowing the Core network and the
EXPLORER 500 to classify packets received from the external network into the proper PDP (Packet
Data Protocol) context.
A TFT consists of from one and up to eight packet filters, each identified by a unique packet filter
identifier. A packet filter also has an evaluation precedence index that is unique within all TFTs
associated with the PDP contexts that share the same PDP address.
Information of source, destination, type of service etc. is combined in each packet filter in the TFT.
Purpose of the Traffic Flow Template
The purpose of the TFT is to assign different priorities to different types of traffic, in order to
optimize performance.
Example: When you are browsing the Internet, a Standard data connection will normally be
sufficient. However, if you need to have a video conference, you may need to use a
Streaming connection, in order to obtain a direct connection without interruptions. Your
Traffic Flow Template can define these priorities, so that your connection automatically
switches to Streaming e.g. when you have a video conference.
