Using traffic flow filters
What are traffic flow filters?
When more than one type of traffic is needed, you must use both a primary and one or more
secondary profiles. For the Core network and the terminal to classify packets received from the
external network into the proper profile, you need a traffic flow filter.
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.
