Priority Code Point (PCP) is a highly available server is an available percentage of the time 99.999%. For packet classification, the VLAN header's 3-bit PCP field is used.
A service's entire performance, including the performance experienced by its users, can be described or measured as having a high quality of service. Examples of such services include cloud computing, telephone, and computer networks.
QoS manages the control and management of network resources and is intended to lessen interference such packet loss, jitter, and latency. Additionally, QoS establishes limitations and order of importance for various data categories that move as bandwidth traffic between IP networks.
In contemporary Layer 2 Ethernet networks, Priority Code Point (PCP) is a technique for categorizing and controlling network traffic as well as for delivering quality of service (QoS). For packet classification, the VLAN header's 3-bit PCP field is used. The IEEE P802 added the PCP field.
