23. ICs utilize flow control technology to throttle the incoming data packet stream and prevent the loss of packets IEEE 803 2x flow control prevents the input buffers of a device from overflowing By using pause frames to communicate buffer status between linked transmitting and receiving devices transmitters and receivers A receiver sends a pause frame to tell a transmitter to stop the transmission of data frames for a specified period allowing the receiver s input port buffers to empty before receiving new packets When a transmitter receives pause frames it suspends transmission for the specified period When the receiver s input buffers can store packets again it can either send another pause frame to tell the transmitter to resume transmission or wait for transmission to resume at the end of the specified period With asymmetric flow control only one of two linked devices can receive pause frames With symmetric flow control both linked devices can send and receive pause frames Related to flow control is the auto negotiation capability in which linked devices advertise their flow control capabilities and automatically select the best common mode of communication Rare cases for example linking to a device that does not support auto negotiation may require that auto negotiation be disabled on a port thereby enabling forced link on that port When forced link is enabled linked devices must have matching flow control capabilities
