QoS Traffic Classification and Marking is the process of identifying and labeling network traffic to ensure proper prioritization and handling across a network. Traffic classification involves analyzing packets based on attributes such as IP addresses, ports, protocols, or application types. Once identified, packets are marked using QoS tags like DSCP or CoS values to indicate their priority level. This helps network devices like routers and switches apply appropriate handling rules for each type of traffic. It ensures that critical applications such as voice, video, and real-time services receive higher priority over less important traffic. This process improves network performance, reduces latency, and ensures efficient bandwidth utilization in enterprise environments.
