Abstract: PURPOSE: A method for determining the number of service channels for data traffic is provided to exactly determine the number of service channels by modelling data traffic and service channels in an M/G/c queuing system. CONSTITUTION: A user initializes a necessary service channel number(S) and receives an added traffic(Erlang)(201). After obtaining a standby time distribution using a diffusion approximating method(202), the user checks whether the obtained standby time distribution satisfies QoS(Quality of Service)(203). If the standby time distribution doesn't satisfy QoS, the user increases the number of service channels(S=S+1)(204). In case that the standby time distribution satisfies QoS, the user outputs the number of service channels(205).
