DEVICE FOR EVALUATING THE FLOW RATE OF VIRTUAL CIRCUITS USING AN ASYNCHRONOUS TIME DIVISION TRANSMISSION CHANNEL

摘要

the incoming cells a path multiplexingasynchronous time are counted by a counter inputfor each virtual circuit, which is incremented at eachvirtual circuit in the cell and which is periodicallydecreased. clock set time unita device for sequentially numbered queue.defines a queue time for each cellthe time unit, a virtual circuit to be useda cell for the inclusion of the identity in thequeue time corresponding cell. a deviceusing the content of command queuetime unit and, at each time unit, identifies a systemvirtual address, and this circuit decrements the countervirtual. the control device also includesprovisions such as virtual circuit whose clockit is in the rest position is assigned to one of thecells to be decreased because of the occurrence of thethe time unit.
