Abstract:
A method for measuring ATM cell rates in a network having a switching system wherein a frequency of occurrence of incoming ATM cells is call-individually acquired comprising the steps of:starting a main part execution upon arrival of a plurality of ATM cells according to a criterion selected from the group consisting of: a) a time threshold TImin that exceeds a predetermined threshold, and b) a frequency threshold CellCountMax that is representative of said frequency of occurrence of said incoming ATM cells that exceeds a predetermined threshold; andstarting a refresh part execution when a predetermined time span has been exceeded;wherein said frequency threshold CellCountMax reflects a maximum plurality of cells per connection that can arrive between two measurements for said same connection without having to implement a rate calculation; andwherein said time threshold TImin is defined as a value between 2 measurements for a connection that must be adhered to when fewer cells than said frequency threshold CellCountMax have arrived for this connection since a last measurement.
