Abstract:
A method of forming a table for use in connection admission control (CAC) for a packet switched telecommunication network, especially for an ATM network, comprising:requesting, by a traffic source, a connection from a network,providing, by a traffic source, parameter values describing the traffic sources' traffic to a network junction having a buffer, wherein a buffer length B and a capacity C of a transfer connection going out from the junction are chosen, and wherein a buffer depletion time T is B/C,forming a table, wherein each line in the table having predetermined values for traffic parameters, the traffic parameters including a peak cell rate, a sustainable cell rate, a burst tolerance and a probability of cell loss,computing traffic parameter ratios using the traffic parameters, andusing the computed traffic parameter ratios to determine an equivalent capacity, wherein the equivalent capacity is generated by using a large deviation approximation and by using a time window length having a time which is twice a buffer depletion time, and whereinvalues proportional to the traffic parameters and the computed equivalent capacity are in the table.
