A compliant IEEE For example, traffic in a client-server environment is dominated by client requests followed by a burst of frames from the server to the requesting client. Although the full duplex environment enables the server to transmit packets while receiving requests from other clients, only a limited number of client requests can be output from amd am79c971 switched hub to the server. If the number of client requests exceeds the capacity of the hub switching port assigned to the server, some of the data packets will be lost.

Alternatively, a client having limited buffer space may be unable to keep up with the transmission rate of the server, resulting in lost packets.

Flow control has been proposed to reduce network congestion, where a sending station temporarily suspends transmission of data packets. A proposed flow control arrangement for a full duplex environment, referred to as IEEE Another proposed flow amd am79c971 arrangement for a half duplex environment, referred to as "backpressure", causes a receiving station to force a collision with the transmitting station when the receive buffer of the receiving station reaches a "receive buffer unavailable" state.

The disclosed flow control proposals, however, reduce the effective bandwidth of the network media. For example, if amd am79c971 full-duplex receiving station repeatedly sends PAUSE frames specifying small pause intervals to a transmitting station, the effective bandwidth of the media is reduced due to the transmission of a plurality of byte PAUSE messages instead of data. For example, if a switched hub has a transmit buffer for data to be sent to a station, repeated transmission of PAUSE frames by the switched hub to that station reduces the removal rate of the data from the transmit buffer. Hence, the transmit buffer containing the data for the station may tend to overflow.

Normally for amd am79c971 on the PCI bus this should always be little endian. This value is zero normally offset This parameter specifies the offset from which the packet has to be loaded from the begining of the device buffer.

Normally this parameter is zero except for architectures which access long words only amd am79c971 aligned addresses. The dual Transmit and Receive FIFOs optimize system overhead, providing sufficient latency tolerance at 10 Mbps and for Mbps systems where low latencies can be guaranteed during frame transmission and reception.
