Abstract
Numerous research has been done on modeling the traffic flows in a multiservice network. An alternative proposal was made by Addie et al. (1998). The authors argued that because the central limit theorem can be applied to heavy traffic processes, therefore as more traffic is aggregated together through the sharing of a transmission link, the aggregated traffic will weakly converge to a Gaussian process. In this paper, we apply this Gaussian model to the connection admission control (CAC) of a multiservice network. We consider a store-and-forward (packet or cell-switched) connection-oriented multiservice network that can be based on the concept of asynchronous transfer mode. We also make efficiency comparison with a CAC based on an effective bandwidth model. Two scenarios were considered: the first assumes that all a priori traffic specifications are known before a CAC acceptance/rejection decision is made, while the second assumes that only the peak rate of a new (requesting admission) connection is declared to the CAC mechanism. The latter scenario entails a measurement-based CAC approach.
对多业务网络中交通流的建模进行了大量的研究。Addie et al.(1998)提出了另一种建议。作者认为,由于中心极限定理可以应用于大流量过程,因此当更多的流量通过共享传输链路聚集在一起时,聚集的流量将弱收敛到高斯过程。本文将该高斯模型应用于多业务网络的连接允许控制(CAC)。我们考虑一个基于异步传输模式概念的面向存储转发(分组或单元交换)连接的多业务网络。并与基于有效带宽模型的CAC进行了效率比较。我们考虑了两种场景:第一种假设在做出CAC接受/拒绝决定之前,所有先验的流量规范都是已知的,而第二种假设只向CAC机制声明新(请求允许)连接的峰值速率。后一种情况需要基于度量的CAC方法。
