Claim 18:
19. A system comprising:
a first network layer device configured to communicate data with a second network layer device over a data transmission medium that comprises a wire, and to perform operations comprising:
establishing an asymmetric data link between the first network layer device and the second network layer device over the data transmission medium, in accordance with a networking standard, data being communicated over the asymmetric data link in a first direction from the first network layer device to the second network layer device at a first data rate, data being communicated over the asymmetric data link in a second direction from the second network layer device to the first network layer device using a second data rate that is lower than the first data rate;
generating, using a first local clock signal of the first network layer device, a first data signal that carries first data, the first data signal being transmitted from the first network layer device to the second network layer device over the asymmetric data link;
receiving, from the second network layer device, a second data signal that carries second data over the asymmetric data link;
extracting the second data from the second data signal by sampling the second data signal using a second local clock signal, the first local clock signal being slower than the second local clock signal; and
communicating with the second network layer device to determine a time for the first network layer device to transmit one or more large data frames to the second network layer device, and to determine a buffer space to be reserved on the second network layer device and used by the second network layer device for receiving the one or more large data frames.
