What type of traffic is typically prioritized in a switched network using QoS?

In a switched network utilizing Quality of Service (QoS), voice and video traffic is prioritized due to its sensitivity to latency, jitter, and packet loss. These types of traffic are real-time applications, meaning they require a steady flow of data without interruptions for optimal performance.

Voice over IP (VoIP) and video conferencing applications need to maintain a consistent bandwidth and low latency to provide clear communication and smooth visual experiences. If this traffic is not prioritized, it may suffer from delays or interruptions, leading to a poor experience for users.

QoS mechanisms are implemented to classify and manage different types of traffic, ensuring that voice and video packets receive higher priority over less sensitive data types like email or file downloads. By prioritizing these real-time communications, networks can efficiently manage bandwidth and keep the quality of service high for critical applications.
