A standard that defines traffic prioritization. 802.1p is now incorporated into the relevant sections of the IEEE 802.1D/D17 standard.

A standard that defines GMRP and traffic prioritization.

Prioritizes network traffic at the data-link/MAC sublayer.

IEEE 802.1p Priority defines up to eight separate traffic types by inserting a tag into a MAC-layer frame that contains bits to define class of service.

An IEEE standard for improving support of time-critical and multicast intensive applications across bridged LANs. An Layer 2 scheme that lets end-stations request priority and network devices enforce it using a tag in the packet header. 802.1p is a key enabler to QoS by enabling "Prioritized Ethernet" with up to 8 priorities in Ethernet networks. It enables Audio/Video traffic on switched Ethernet fabrics. The eight discrete priority levels range from the default of best effort, through excellent effort (a business-critical application, but tolerant of some delay), interactive multimedia (sensitive to delay or jitter), and reserved (highest priority). Incorporated into and superceded by IEEE 802.1D.

An IEEE standard for prioritizing time-critical flows and filtering multicast traffic to contain traffic in layer-two networks. The 802.1 p header includes three bits for prioritization, allowing for eight priorities to be established.

A standard that provides quality of service (QoS) in Ethernet networks. It relies on packet tags and allows switches to transmit packets in order of priority.

Standard for quality of service; network traffic prioritization.

IEEE 802.1p is a standard that provides traffic class expediting and dynamic multicast filtering. Essentially, it provides a mechanism for implementing Quality of Service (QoS) at the MAC () level.
