    摘要： A network component for processing a packet can include a buffer configured to receive a packet in an ingress port at a network component, a first identification unit configured to identify a destination address and a network identifier from the packet received at the buffer, and a look-up table configured to be indexed by the destination address and the network identifier identified by the identification unit to obtain an outgoing port bit map. In addition, the network component can include a forwarding unit configured to forward the packet to a destination module and out of an egress port within the network component based on the outgoing port bit map.

    摘要： A network device for implementing VLAN translation on a packet. The network device includes a user network interface port for receiving and transmitting packets to customers of a network. The network device also includes a network to network interface port for communicating with a second network device in the network. A packet received at the user network interface port is classified, translated based on a predefined provider field associated with the packet, and encapsulated with a tag that is removed when the packet is transmitted from the user network interface port to a customer.

    摘要： A network device for implementing mirroring on packets. The network device includes a plurality of ports, each of which is at least one of an ingress port, an egress port and a mirror-to port. The network device also includes processing means for supporting a plurality of mirroring types. Each of the ingress port, egress port and mirror-to port includes at least one register for supporting the plurality of mirroring types. To support mirroring at each of the ingress port, egress port and mirror-to port predefined bits in the at least one register are set. When an incoming packet is received, the predefined bits are examined to determine which of the plurality of mirroring types to apply to the packet.
