What is the primary purpose of QoS in Cloud RAN networks?

The primary purpose of Quality of Service (QoS) in Cloud Radio Access Networks (RAN) is to prioritize different types of traffic for optimal performance. In a Cloud RAN environment, various types of applications and services are accessed by users, each with distinct requirements regarding latency, bandwidth, and reliability. QoS mechanisms allow the network to classify and manage traffic based on these requirements.

By prioritizing traffic, QoS ensures that critical applications—such as voice calls or real-time video streaming—receive the necessary resources to function effectively, even in congested network situations. This means that network operators can optimize the overall user experience by ensuring that high-priority traffic is handled preferentially, while lower-priority traffic may experience some delay or reduced performance without significantly impacting user satisfaction for critical services.

While lowering latency, enhancing bandwidth, and facilitating error correction are important aspects of network performance, they are more specific outcomes or functions that can be influenced by QoS policies rather than its primary purpose. QoS's main goal is the prioritization of traffic to meet the varying service level agreements and user expectations across the network.
