802.1p

An IEEE standard for providing quality of service (QoS) in 802-based networks. 802.1p uses three bits (defined in 802.1q) to allow switches to reorder packets based on priority level. It also defines the Generic Attributes Registration Protocol (GARP) and the GARP VLAN Registration Protocol (GVRP). GARP lets client stations request membership in a multicast domain, and GVRP lets them register into a VLAN. See IEEE 802 and QoS.

Along with support for more traditional features such as port-based VLANs, IEEE 802.1p QoS, 802.1x port security, link aggregation, and port mirroring, the IE200 Series also supports innovative features such as Ethernet Protection Switched Ring (EPSRingTM) and Allied Telesis Management Framework (AMF).
CFIP Lumina supports also QOS (Quality of Service) which can be configured in 4 priority queues whether using DIffServ (DSCP) or 802.1p mapping.
An embedded Layer 2 Ethernet switch provides advanced QoS and traffic management features such as 802.1p and DiffServ support, 802.3x flow control and 802.1q VLAN support.
The simple Web-based configuration provides support for 802.1Q Tag and Port-based VLAN; 802.1p Quality of Service traffic prioritization; port mirroring as well as specific port configurations.
In addition, the switches support 802.1Q VLAN tagging for traffic segmentation by groups, and 802.1p Priority Queues.
Look for switches that comply with the IEEE 802.1p standard.
The BCM1113R's integrated Ethernet switch enables a desktop PC and IP phone to share a single LAN connection, and supports both IEEE 802.1p packet prioritization and 802.1q VLAN identification.
Quality of service (QoS) is maintained in a wireless grid infrastructure without compromising security through high-performance micro-cells and extensive support for QoS standards such as 802.11e, Diffserv and 802.1p. In addition, centralized stateful application classification ensures that delay and jitter-sensitive applications such as voice receive the appropriate QoS treatment in a wireless grid.
