The priority value (PV) is set for each traffic stream that is to be switched to green. It consists of three parts:

  • The basic priority depends on the priority element in which the traffic stream is processed.

PV = (maximum number of priority elements - position in the processing sequence) * 100

  • Added to this is its rank as a minor stream

PV = PV + Maximum number of secondary streams - Current rank + 1

  • In addition, the value can be further increased via the priority flag parameter.

PV = PV + priority value * 1000
