Quality of Service
and the following page appears.
Under
Quality of Service
, there are two network share modes:
Queue Config
and
QoS Classification
.
Network QoS is an industry-wide set of standards and
mechanisms for ensuring high-quality performance for critical
applications. By using QoS mechanisms, network
administrators can use existing resources efficiently and
ensure the required level of service without reactively
expanding or over-provisioning their networks.
Traditionally, the concept of quality in networks meant that all
network traffic was treated equally. The result was that all
network traffic received the network’s best effort, with no
guarantees for reliability, delay, variation in delay, or other
performance characteristics. With best-effort delivery service,
however, a single bandwidth-intensive application can result in
poor or unacceptable performance for all applications. The
QoS concept of quality is one in which the requirements of
some applications and users are more critical than others,
which means that some traffic needs preferential treatment.

4.4.5.1 Enabling QoS
In this page, you can perform QoS queue management
configuration. By default, the system enables QoS and sets a
default DSCP mark to automatically mark incoming traffic
without reference to particular classifier.
