Abstract
A method and controller for sending data frames over a lossy bidirectional link between integrated circuit chips is disclosed. Upon transmission, frames are stored in a buffer. The detection of errors is indicated and triggers retransmission of the erroneously received frame, but acknowledgement of correctly received frames is not indicated. Instead, the sending controller assumes that frames were correctly received if no error indication is received after a period of time. The period of time is the maximum amount of time that would be taken for the sending controller to receive an error indication if the frame was received with an error. After said period of time, the sent frame is discarded from the buffer.
