📄️ QoS
QoS, or Quality of Service, is a set of network techniques used to classify, prioritize, and manage traffic during congestion. QoS helps protect latency-sensitive and business-critical applications such as voice, video, and interactive services.
📄️ QoS monitoring
QoS monitoring analyzes network performance and traffic behavior to understand how latency, jitter, congestion, packet loss, throughput, and queue conditions affect application responsiveness and service quality across network environments.
📄️ Quality of experience
Quality of Experience (QoE) measures how users actually perceive application responsiveness, communication quality, stability, and service usability under real network and operational conditions rather than relying only on infrastructure metrics.
📄️ Queueing
Queueing is the temporary holding of packets when a device or link cannot forward them immediately. Queueing is a normal part of packet forwarding, but excessive queue buildup can increase latency, jitter, congestion, and packet loss.
