PIR—Peak information rate. The PIR specifies the maximum rate allowed by the target VMs to transmit or
forward packets. If the traffic bandwidth exceeds the PIR value, the system discards the redundant
packets to control the bandwidth.
Q
QoS—Quality of service. QoS is, in the networking industry, using specialized tools to monitor and
identify different types of network traffic, voice, video, and to establish priority and througH3Cut levels
