A first network device includes a host and a memory. A media access controller receives data from the host and stores the data in the memory at a first rate. A physical-layer device receives the data from the memory and transmits the data from the first network device to a second network device. The memory is connected between the media access controller and the physical-layer device. An amount of the data stored in the memory is based on the first rate and a second rate at which the physical-layer device transfers the data from the memory to the second network device. The first rate is greater than the second rate. A control circuit, based on an amount of the data stored in the memory, transmits a first frame to the media access controller. The media access controller, in response to the first frame, decreases the first rate. |
