In a network that carries diverse types of traffic like data, voice, and video, ensuring the performance

of latency-sensitive applications such as voice and video calls is crucial. Class of Service (CoS) is a

technology designed to prioritize network traffic, ensuring that critical applications like voice and

video receive the necessary bandwidth and minimal latency. CoS mechanisms can include traffic

classification, traffic policing, queue management, and scheduling. By implementing CoS, network

administrators can assign higher priority to voice and video traffic, thus improving their performance

across the network and addressing the users' complaints about call quality.
