QoS for Voice and Video refers to the use of Quality of Service techniques to optimize real-time audio and video communication over a network. It ensures smooth transmission by prioritizing voice calls and video streams over regular data traffic. QoS reduces latency, jitter, and packet loss, which are critical factors that affect call and video quality. Network administrators use methods such as traffic classification, DSCP marking, bandwidth reservation, and low-latency queuing to manage traffic efficiently. These techniques help maintain clear audio, stable video playback, and uninterrupted communication during high network usage. QoS for Voice and Video is essential in VoIP, video conferencing, streaming, and enterprise collaboration environments.
