What is the benefit of configuring Quality of Service (QoS) in a switched network?

Configuring Quality of Service (QoS) in a switched network primarily benefits the network by prioritizing certain types of traffic. This prioritization ensures that critical applications receive the necessary bandwidth and latency required for optimal performance. For instance, applications such as VoIP, video conferencing, and real-time data transmissions are sensitive to delays and packet loss. By implementing QoS policies, network administrators can classify, manage, and prioritize traffic flows so that important data packets are transmitted promptly, reducing the likelihood of interruptions or degradations in service quality for these applications.

This traffic shaping is essential in environments where bandwidth is limited, helping to maintain a seamless experience for users and applications that are critical to business operations. Prioritization through QoS allows for a more efficient use of network resources, ultimately improving overall network reliability and user satisfaction.
