QoS (Quality of Service) on Routers and Switches refers to network techniques used to manage and prioritize data traffic for optimal performance. It ensures that critical applications such as voice, video, and real-time services receive higher priority over less time-sensitive traffic. Routers and switches use QoS policies to control bandwidth allocation, reduce latency, and minimize packet loss. This helps maintain consistent network performance even during high traffic loads. QoS mechanisms include traffic shaping, classification, and queuing strategies. It is essential in enterprise networks to ensure reliable communication and efficient resource utilization.
