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
Shaping network traffic
Setting traffic priorities across the network
The Best-Effort service is the default QoS model in IP networks. It provides no
guarantees for data delivering, which means delay, jitter, packet loss and bandwidth
allocation are unpredictable. Differentiated Services (DiffServ or DS) is the most widely
used QoS model. It provides a simple and scalable mechanism for classifying and
managing network traffic and providing QoS on modern IP networks. Differentiated
Services Code Point (DSCP) is used to define DiffServ classes and stored in the first six
bits of the ToS (Type of Service) field. Each router on the network can provide QoS
