Title:
QUEUE SCHEDULING DEVICE, QUEUE SCHEDULING METHOD AND INFORMATION RELAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/072538
Kind Code:
A1
Abstract:
A dequeue execution section basically shifts to readout a next queue after dequeuing one
frame. When a deficit value controlled in a deficit processing section becomes 0
in queue, the queue is excluded from a scheduling (dequeue) subject but a deficit value
that is not less than 0 in queue, i.e., a queue that still includes a frame, is only
subjected to the execution of a dequeue in turn. When all the queues are excluded
from scheduling subjects, the deficit processing section resets the deficit
value by a quantum value and returns to an initial state. A burst size at the dequeue
can be suppressed to be one frame.
