Description: Overhead delay is the time it takes to process additional information needed to manage a network service. This concept is fundamental in the realm of Quality of Service (QoS), as it refers to the latency introduced when handling extra data, such as packet headers and control information. In a network environment, each data packet sent may require additional processing to ensure that QoS policies are met, which may include prioritizing certain types of traffic or implementing security measures. This delay can be critical in applications that require low latency, such as real-time video streaming or VoIP communications, where any additional delay can affect the quality of the user experience. Furthermore, overhead delay can vary depending on network architecture, types of devices involved, and complexity of the QoS policies implemented. Therefore, understanding and managing overhead delay is essential for optimizing network performance and ensuring that the quality standards expected by end users are met.
