<p>PROBLEM TO BE SOLVED: To obtain an excellent transmission characteristic by setting a threshold strictly. SOLUTION: In the case that queue information with respect to respective queues is fetched from a queue length measurement section 8 in this variable queue length control method, an output queue decision section 9 receives a notice of a queue number to output an output queue. Variable threshold control is a processing among a plurality of queues with respect to a same output port and this threshold has information that is used to discriminate to which of output ports 1-4 the queue number received in advance from the output queue decision section 9 belongs or whether or not an optional queue belongs to the output port. In the variable threshold processing, a threshold, before the queue length information is revised by an output of the queue number from the output queue decision section 9 where the queue length information received from the queue length measurement section 8 is used for a processing trigger, is executed.</p> |
