A QoS policy is a set of rules and configurations used to manage and prioritize network traffic based on various criteria, ensuring that critical applications receive the necessary bandwidth and performance while less important traffic is deprioritized. This is particularly important in environments where different types of traffic, such as video streaming, voice over IP, and data transfers, compete for limited network resources. The effective implementation of QoS policies helps maintain the overall quality of experience for users by minimizing latency, jitter, and packet loss.
congrats on reading the definition of QoS Policy. now let's actually learn it.
