Using traffic flow filters
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 IP connection is normally sufficient.
However, to have a video conference you may need a Streaming IP connection in order
to obtain a direct connection without interruptions. Your traffic flow filters can define
these priorities, so that your connection is automatically set to Streaming e.g. when you
have a video conference.
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 BGAN 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 packet filter 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. The evaluation precedence index determines the
order in which the filters are applied; 0 is applied first, then 1 and so forth. Information of source,
destination, type of service etc. is combined in each packet filter in the list.
