￿

Queue mode shall be set to control the sequence of outputting a packet to the

transmission queue in the interface. The queue mode includes the following five

catergories: output priority control, minimum band assurance, uniformity

assurance, minimum uniformity band assurance, and minimum band assurance

(kbps designation). The definition method defines a queue list to be set in the

transmission queue of the interface by using the QoS attribute (qos-queue-list)

and further sets a queue list to be used on each interface by using the QoS

interface information (qos-interface).

Interlocking with QoS queue control

￿The queue control is a function that discards a packet to be stacked on the transmission queue according to the queuing priority if the packet is stagnating in the transmission queue. The function sets the pattern of queue length permitting the queuing on each queuing priority by using the QoS discard mode (qos-discard-mode).
