Abstract
Packet flow control is performed in a device having a packet memory, where the device is for connecting to a plurality of remote devices. Port interface devices transmit packets to and receive packets from the remote devices, respectively. Port controllers generate a packet flow control request signal that is active when the packet memory is in an overflow condition and generate a packet transmission request signal that is active when a packet stored in the packet memory is to be transmitted to at least one of the remote devices. Media access control (MAC) devices execute a packet flow control operation when the packet flow control request signal generated by the port controllers is active. The packet flow control operation includes transmitting a given bit stream to the remote devices via the respective port interface devices, and aborting the transmission of the given bit stream and transmitting a packet from the packet memory when the packet transmission request signal becomes active while the packet flow control request signal is active.
