Abstract

See full text

A traffic shaper that feeds cells into an asynchronous-transfer-mode virtual-path-switching network has two queues per virtual path: a first queue providing a regular class of service, and a second queue providing a variable class of service. Cells are taken from the first queue in preference to the second queue, combined traffic from the two queues is kept within a peak cell rate, and traffic from the second queue is kept within an allowed cell rate. Forward resource-management cells are inserted at certain intervals in the cell flow taken from the second queue, and the allowed cell rate is adjusted according to backward resource-management cells received in reply. A third queue for priority cell traffic, limited to a priority cell rate lower than the peak cell rate, may also be provided.
