Abstract:
1. A method for predicting a fill-up level of a buffer in an ATM network element, wherein for a respective one of at least one ongoing transmission connection via said ATM network element, cells are input to said buffer with a respective input cell rate, and said ATM network element outputs said cells at a predetermined output cell rate, the method comprising: measuring a momentary fill-up level of said buffer after each respective time interval; determining a slope of the fill-up level of said buffer for an immediately preceding time interval; and estimating the fill-up level of said buffer to be reached after a subsequent time interval based on said slope of the fill-up level for the immediately preceding time interval; wherein said momentary fill-up level of said buffer is measured based on a delay time experienced by a specific cell input to said buffer at a first time until said specific cell is output from said buffer at a second time.
