Abstract: In a method for administration of priorities of routes in a telecommunications network, for converting priority values of various routes from an actual condition into a target condition, a request for defining its priority value is implemented for each route defined in the target condition that has one of the priority modes “EQUAL” or “INSERT” as a parameter. The requests are executed in the sequence of decreasing priority, and the priority mode “insert” is employed for the respectively first request for fixing on a given priority value. The priority mode “EQUAL” is selected for every further request for fixing on the same priority value.
