These standards define tags that extend the 802.3
(Ethernet) frame to include a 3-bit priority indicator (802.1p) and a 12-bit
Virtual LAN (VLAN) identifier (802.1q). The 3-bit priority indicator can be
used to prioritize the treatment of frames within the network, e.g. scheduling
priority within an Ethernet switch, buffer-allocation quota etc. The VLAN tags
partition a physical LAN into multiple logical LANs to enhance administration,
security as well performance of the logical LANs.
