Abstract:
1. A method for frame retransmission in a physical layer device, comprising: establishing a link between a local physical layer device and a remote physical layer device, said local physical layer device and said remote physical layer device being coupled via a network cable; transmitting an Ethernet frame over said established link to said remote physical layer device; identifying a need to retransmit said Ethernet frame to said remote physical layer device transmitting a link interruption signal from said local physical layer device to a local media access control coupled to said local physical layer device, said transmitted link interruption signal alerting said local media access control to hold off transmission to said local physical layer device, retransmitting said Ethernet frame to said remote physical layer device while said local media access control is holding off transmission based on said transmitted link interruption signal; and after said retransmission is complete, de-asserting, by said local physical layer device,said link interruption signal, said de-asserting enabling said local media access control to resume transmission to said local physical layer device.
