Abstract: A method of managing oversubscription of a common buffer resource shared by a number of traffic flows in a cell switching network in response to the utilization of the common buffer resource. A buffer utilization threshold is established for each of the traffic flows. As new cells arrive, the global usage of the buffer resource is monitored. As the buffer utilization increases, the thresholds for each of the traffic flows are dynamically adjusted based upon the global usage of the buffer. Aggressive buffer allocations are scaled back when necessary, thereby leaving space for traffic flows which are relatively empty. In one embodiment, the thresholds are coded in mantissa and exponent form so that the scaling is accomplished by adjusting the exponent value.

Abstract translation: 响应于公共缓冲器资源的利用，管理由小区交换网络中的多个业务流共享的公共缓冲资源的超额预订的方法。 为每个业务流建立缓冲区利用率阈值。 当新的单元到达时，监视缓冲资源的全局使用情况。 随着缓冲区利用率的增加，每个业务流的阈值都会根据缓冲区的全局使用情况进行动态调整。 必要时可以缩放积极的缓冲区分配，从而为相对空的流量流留出空间。 在一个实施例中，阈值以尾数和指数形式编码，使得通过调整指数值来实现缩放。
