Quality of Service (QoS) is the ability to provide different priorities for different packets
in the network. This allows the transport of traffic with special requirements. QoS
guarantees are important for applications that require a fixed bit rate and are delay
sensitive when the network capacity is insufficient. There are four major QoS factors to
be considered when configuring a modern QoS implementation: bandwidth, delay,
jitter and loss.
QoS provides a better network service through the following features:

Supporting dedicated bandwidth

Improving loss characteristics

Avoiding and managing network congestion

Shaping network traffic
