基于IBP信源模型的ATM网络连接允许控制

CONNECTION ADMISSION CONTROL BASED ON THE IBP SOURCEMODEL IN ATM NETWORKS

本文提出了一种简单、有效的连接允许控制方法，该方法是采用ＩＢＰ业务模型和ＡＴＭ节点的虚路径缓冲器和容量参数，通过在线计算信元丢失概率的上限来实现的。由于ＩＢＰ模型中的信元到达时间间隔的分布具有解析特性，使得基于ＩＢＰ模型的信元丢失概率的上限计算问题得到简化，增强了允许控制的实时性。

This paper presents a simple and effective connection admission control scheme. It is implemented by online calculating of the upper bounds of cell loss probability based on the IBP traffic source model and the parameters of the buffer and capacity of a virtual path in ATM node. Due to the analytic characteristic of the cell arrival interval in IBP model, it makes the calculation of the upper bounds of cell loss probability simple and improves the realtime characteristic of connection admission control.
