A way to calculation effective bandwidth based on Liner Fractional Stable Noise（LFSN） is studied, and the formula for effective bandwidth of admitted aggregated traffic sources is derived according to iterative conception. A CAC （call admission control） algorithm of self-similar traffic based on equability is proposed. The equality mechanism is introduced in the admitting deterministic process, thus to ensure the equality in admitting the traffic. Simulation has proved the effectiveness of CAC, and the proposed method can guarantee QoS of the network, ensure the fairness in the traffic admission, while maintaining the high utilization of the network.
