How are congestion control and quality of sercives related to one another?

Congestion control and quality of service (QoS) are interconnected in network management. Congestion control mechanisms aim to prevent network overload by regulating data flow, ensuring that the network can handle traffic without significant delays or packet loss. In contrast, QoS techniques prioritize certain types of traffic to guarantee a minimum level of performance for critical applications, such as voice or video. Effective congestion control can help maintain the QoS by minimizing latency and ensuring reliable delivery of prioritized data streams.
