This allows the transport of traffic with special requirements. QoSguarantees are important for applications that require a fixed bit rate and are delaysensitive when the network capacity is insufficient. There are four major QoS factors tobe 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 Setting traffic priorities across the network
