What is the highest priority level for DSCP tags?

The highest priority level for Differentiated Services Code Point (DSCP) tags is indeed associated with Level 4. DSCP is a networking protocol used to classify and manage packets in IP networks by assigning a specific value that indicates the priority of the data being transmitted. The DSCP values are derived from the 6-bit field in the IP header, which translates into various priority levels and traffic categories.

In DSCP, the values range from 0 to 63, where higher values correlate with higher priority. Level 4, often referred to in practical terms as Expedited Forwarding (EF), is designated for low-loss, low-latency traffic such as voice or video. This priority ensures that time-sensitive data is transmitted with minimal delay, providing a better quality of service.

Thus, understanding the context of DSCP and its application in prioritizing network traffic highlights why Level 4 represents the highest priority level for DSCP tags. This prioritization is critical for applications where maintaining service quality is paramount, such as VoIP communications or streaming media.
