ABSTRACT:
A buffer management system and method for use in an ATM switch that allows for data processing of variable bit rate (VBR) and constant bit rate (CBR) traffic using a common buffer memory. The buffer memory is broken down into data sub-queues, each of which is assigned an output and purge priority. ATM cells are allocated to a particular data sub-queue by matching the desired quality-of-service of the cells with the output and purge characteristics of each sub-queue. The system and method dynamically sizes the data sub-queues so as to be equal to the number of ATM cells in the data sub-queue. In addition, age and size ratio thresholds may be assigned to each data sub-queue to better distribute available bandwidth among the sub-queues, and to ensure that cells are not excessively delayed.
