7.2.4.2 QoSStatistics
QoS (Quality of Service) characterizes the entire network performance which is defined by the parameters such as:
throughput, latency, jitter, error rate, available bandwidth, etc. In order to provide the guaranteed Quality of
Service for certain applications, users or data flows, different prioritization methods are used.
The "QoSStatistics" tool displays the statistics of the MINT priority queues for the interface.
Priority is one of the parameters which define in what sequence, different types of data traversing every InfiNet
device in MINT network are treated. Each channel may be assigned a priority (for example: P01, P02 … P16).
Once assigned, a priority is automatically recognized by every node inside the MINT network. Each priority value
corresponds to a device queue. Once in a queue, every packet is scheduled according to the queuing algorithm set
on the device. QM manager supports Strict Priority Queuingand Weighted Fair Queuingscheduling algorithms.
Strict Priority Queuingmeans that the packets from queue with lower priority are not processed until the queue
with higher priority is not empty. Weighted Fair Queuinguses weights for every queue of an interface and allows
different queues to have different service shares, depending on that weight.
Every channel is also characterized by the latency parameter. This parameter determines the maximum time for the
packets to stay in the channel. If a packet is waiting in a queue of the channel more than the time specified in the
latency parameter, then it is discarded. Latency can be set for each channel in the "
Traffic Shaping (see page 136)"
section.
