Abstract
A line interface card apparatus includes: a packet queue memory for storing packets; a physical layer having first and second buffers, the physical layer being connected to the packet queue memory by a data bus and being connected to a plurality of links; and a queue manager connected to the packet queue memory and to the physical layer by a control bus. Upon one of the plurality of links transmitting a request for data packets to the physical layer, the physical layer transmits the request via the control bus to the queue manager; the queue manager instructs the packet queue memory to transmit requested data packets to the physical layer via the data bus; each data packet is transmitted from the packet queue memory to the physical layer in one or more packet fragments which are stored in one of the first and second buffers, and upon all of the one or more packet fragments of one data packet being stored in one of the first and second buffers, the data packet is transmitted to the link transmitting the request for data packets.
