Detailed Description

QoS cluster configuration structure for Modified Token Bucket.


Field Documentation

uint32_t Qmss_QosClusterCfgTB::maxGlobalCredit

The maximum amount of global credit allowed to carry over to the next queue. Excess global credit is discarded

uint8_t Qmss_QosClusterCfgTB::qosQueCnt

The number of QOS queues in this cluster. Valid range is 1 to QMSS_QOS_MAX_QUE_PER_CLUSTER_COUNT

uint8_t Qmss_QosClusterCfgTB::qosQueNum[QMSS_QOS_MAX_QUE_PER_CLUSTER_COUNT]

The queue index (0 to 63) of each QOS queue in the cluster listed in priority order. These queue indices are relative to the configured QOS queue base index Ensure that the queue base passed into Qmss_setQosQueueBase supports the size of the queue index provided (eg some devices allocate fewer than 64 queues).

uint16_t Qmss_QosClusterCfgTB::qosQueRTFlags

This 9-bit mask contains 1 bit for each QOS queue in the cluster. When this bit is set for its corresponding QOS queue, iteration credit is treated as "real time" scheduling and does not scale when the egress queue become congested

uint8_t Qmss_QosClusterCfgTB::egressQueCnt

The total number of egress queues sampled to obtain the egress queue congestion estimation. Valid range is 1 to QMSS_QOS_MAX_QUE_PER_CLUSTER_COUNT

Qmss_Queue Qmss_QosClusterCfgTB::egressQueNum[QMSS_QOS_MAX_QUE_PER_CLUSTER_COUNT]

The Queue manger and Queue index of every egress queue enumerated in Egress Queue Count. These queue indices are absolute index values

uint32_t Qmss_QosClusterCfgTB::egressCongestionThreshold1

Egress Congestion Threshold point 1

uint32_t Qmss_QosClusterCfgTB::egressCongestionThreshold2

Egress Congestion Threshold point 2

uint32_t Qmss_QosClusterCfgTB::egressCongestionThreshold3

Egress Congestion Threshold point 3

uint32_t Qmss_QosClusterCfgTB::egressCongestionThreshold4

Egress Congestion Threshold point 4
