Using traffic flow filters
What are traffic flow filters
Traffic flow filters allow the Core network and the terminal to classify packets
received from the external network into the proper profile.
A list of traffic flow filters consists of one 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 traffic flow filters associated with
the profiles that share the same PDP (Packet Data Protocol) address.
Information of source, destination, type of service etc. is combined in each
packet filter in the list.
Purpose of the traffic flow filters
The purpose of the traffic flow filters 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 is
normally sufficient. However, to have a video conference you may
need a Streaming connection in order to obtain a direct connection
without interruptions. Your traffic flow filters can define these
priorities, so that your connection automatically switches to
Streaming e.g. when you have a video conference.
