Quality of Service
Many communication and multimedia applications require large, high-speed bandwidths to transfer data between the local network and the internet.
However, for many applications there is often only one internet connection available with limited capacity. QoS divides this capacity between the
different applications and provides undelayed, continuous data transfer in situations where data packets with higher priority are given preference.

and the following page will appear. 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.
