Abstract
In the transmission of ATM cells, there is often the requirement to: This measurement is usually implemented within a fixed time interval but this can be problematical insofar as this type of measurement leaves the type of connection out of consideration. The invention alleviates this situation in that the traffic characteristic of the ATM cells functions as the criterion for when a measurement is to be implemented.
Claims4
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;
- and
- starting 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;
- and
- wherein 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.
