Abstract:
A method for optimizing a load level on connection sections for VBR traffic, comprising the steps of:transmitting ATM cells which are associated with said VBR traffic between a transmitting device and a receiving device via common connection sections: measuring the frequency of said ATM cells on a connection-specific basis; calculating a first value independently of an instantaneous load on a connection section, the first value representing long-term load conditions on the connection section; assigning said first value to a connection; estimating a second value on the basis of a measured line load level, the second value representing short-term load conditions on the connection section; and setting an explicit cell rate on a connection-specific basis by a control method, wherein said explicit cell rate is greater than or equal to said first value and less than or equal to the larger of said first value and second value, wherein said explicit cell rate is closer to said first value when a memory filling level is high, and wherein said explicit cell rate is closer to the larger of said first value and said second value when said memory filling level is low.
