Patent ID: 8542608

Claim:
A method in a communication network node of achieving an optimal initial shaping rate for a new packet flow on a transport network between said communication network node and a second communication network node in a communication network system, characterized in that, the method comprises the steps of: determining, by a processor, shaping rates of ongoing packet flows on said transport network, the said shaping rate of said new packet flow being determined by calculating a fairness optimal initial shaping rate from capacity allocations “CA” of ongoing flows; selecting, by the processor, based on said determined shaping rates of ongoing packet flows, an initial shaping rate for said new packet flow so as to obtain a maximized fairness among all shaping rates, the fairness optimal initial shaping rate being calculated using the formula Avg(CA)+Var(CA)/Avg(CA), wherein Avg(CA) is an average shaping rate of ongoing flows and Var(CA)/Avg(CA) is the relative variance of a shaping rate of ongoing flows.
