Priority code point, also known as PCP, is a term commonly used in the world of networking and telecommunications to describe a specific part of the quality of service (QoS) mechanism. However, there are several other phrases and synonyms that can be used to describe priority code point, such as Traffic Class, Differentiated Services Code Point (DSCP), Traffic Priority, QoS level, and Service Class Identifier (SCI). Each of these terms essentially refers to the same thing: a specific value assigned to network traffic to indicate its level of priority and to ensure that it is given the appropriate level of treatment in congestion scenarios. Regardless of the specific term used, priority code point is an important part of maintaining high-quality network performance.
