Quality of Service (QoS)
Quality of Service (QoS) is the ability to provide different priorities for different packets in the
network, allowing the transport of traffic with special requirements. QoS guarantees are
important for applications that require 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 better network service through the following features:

Supporting dedicated bandwidth

Improving loss characteristics

Avoiding and managing network congestion
