802.1p. This standard is a mechanism that allows real- time traffic classification into 8 priority levels mapped to 4 queues. Packet classification is based on TOS, DSCP, MAC, IPv4, VLAN ID, TCP/UDP port number, protocol type and user defined packet content, which enables flexible configuration especially for real-time streaming multimedia applications such as voice over IP.
