Extended Priority for Ethernet Packets |
摘要 |
A network device includes a packet ingress configured to receive packets from a network, and a packet processor configured to identify a first packet of the received packets as a double VLAN tagged packet with an extended priority profile. The packet processor is also configured to determine, based on P bits distributed among M bits of a first priority field associated with a first VLAN tag and N bits of a second priority field associated with a second VLAN tag, the extended priority profile of the first packet from among a group of possible extended priority profiles that is larger than a first group of possible priority profiles associated with the first priority field and larger than a second group of possible priority profiles associated with the second priority field. The packet processor is also configured to process the first packet according to the determined extended priority profile. |

1. A network device comprising:
a packet ingress configured to receive packets from a network; and a packet processor configured to
identify a first packet of the received packets as a double VLAN tagged packet with an extended priority profile,determine, based on P bits distributed among (i) M bits of a first priority field associated with a first VLAN tag of the first packet and (ii) N bits of a second priority field associated with a second VLAN tag of the first packet, the extended priority profile of the first packet from among a group of possible extended priority profiles that is (i) larger than a first group of possible priority profiles associated with the first priority field and (ii) larger than a second group of possible priority profiles associated with the second priority field, andprocess the first packet according to the determined extended priority profile. |
