Quality of Service (QoS) is chiefly used by networks that oversee data traffic for resource-intensive systems.
These networks implement QoS to manage traffic flow and prioritize certain types of data, ensuring consistent performance for applications that are sensitive to delays and network congestion. This is critical for maintaining high quality for services that require guaranteed bandwidth and low latency.
Types of Systems Requiring QoS
Networks deploying QoS typically support a variety of resource-intensive applications and services. According to the provided reference, these services include:
- Internet Protocol TV (IPTV)
- Online Gaming
- Video Conferencing
- Voice over Internet Protocol (VoIP)
- Video and Audio Streaming
- Video on Demand
Without QoS, the quality of these services can deteriorate significantly when network traffic is high, leading to issues like stuttering video, dropped calls, or laggy online games. By using QoS, network administrators can ensure that traffic from these critical services receives preferential treatment over less time-sensitive data, such as email or file downloads.
