【Abstract】 The call admission control problem based on Gaussian mixture model in ATM communication network is studied. A Gaussian mixture model is proposed to approximate the probability density function of aggregated traffic flow distribution. The EM algorithm is used to estimate the parameters of the hybrid model and the admittance control formula based on the Gaussian mixture model is derived.
