Description: Delay metric is a crucial measure in the field of quality of service (QoS) in communication networks. It refers to the time it takes for a data packet to travel from its source to its destination. This delay time can be influenced by various factors, such as the physical distance between the source and destination points, network congestion, processing in intermediate devices, and the inherent latency of the transmission media used. The delay metric is fundamental for evaluating network performance, as excessive delay can negatively impact user experience, especially in real-time applications like video conferencing, online gaming, and audio streaming. In this sense, minimizing delay is sought to ensure smooth and efficient communication. Additionally, delay can be broken down into several components, such as transmission delay, propagation delay, queuing delay, and processing delay, allowing network engineers to identify and address specific issues that may be affecting service quality. In summary, the delay metric is a key indicator that helps network administrators optimize performance and the quality of user experience in digital communication environments.
