用于自相似业务的一种CAC

A Novel CAC Algorithm under Self-similar Traffic

针对网络业务的自相似特性，在高斯假设下得到了该特性下的业务排队性能；提出了一种适用于传统业务和自相似业务的呼叫接纳控制算法。仿真表明了该算法具有速度快、参数简单等优点。

Recent studies of the network show that the self-similar nature of the traffic has large influences on the network performance. Based on the traditional traffic models, the network performance is often over optimism. In this paper, a formula of cell loss rate of a buffer system under the self-similar traffic is proposed. A call admission control algorithm utilizing the Gaussian assumption of the traffic is given, which deals with the traditional traffic and self-similar traffic as well. Simulation results indicates that this algorithm is rather accurate and fast.
