摘要

A method for transmitting a packet on a logical port comprising two or more physical ports comprises receiving a packet of a class of service; storing the packet in a memory; maintaining a lookup table relating a plurality of identifiers to at least one physical port; storing a pointer to the stored packet in the memory in a single pointer list for the class of service along with a selected one of the identifiers; and copying the stored packet to one or more physical ports corresponding to the selected identifier for transmission on at least one of the physical ports. In one implementation, a plurality of the physical ports are grouped into a logical port, and the received packet is processed to determine its logical port and its class of service.

1. A method for transmitting a packet on a logical port comprising at least two physical ports, said method comprising:
receiving a packet of a class of service; storing said packet in a memory; maintaining a metadata lookup table relating a plurality of identifiers to at least one of said physical ports, said maintaining comprising updating said metadata lookup table when there is a change in at least one of said physical ports; storing a pointer to the stored packet in said memory in a single pointer list for said class of service along with a selected identifier of said plurality of identifiers; and copying the stored packet to one or more of said physical ports corresponding to the selected identifier for transmission on at least one of said physical ports.
