UDP (User Datagram Protocol) does not have any built-in mechanisms for Quality of Service (QoS) management. This means that UDP does not provide any guarantees for packet delivery or packet loss, and the sender has no control over the order of packet delivery.
However, some applications that use UDP might provide their own implementation of QoS. For example, voice over IP (VoIP) applications may use UDP but may also implement QoS by prioritizing and queuing packets based on their importance, and ensuring low-latency and minimal packet loss.
In such cases, the application layer is responsible for implementing QoS features to ensure better performance, rather than relying on the transport layer protocol itself.
