METHOD AND SYSTEM FOR EXTENDING THE REACH OF A DATA COMMUNICATION CHANNEL USING A FLOW CONTROL INTERCEPTION DEVICE

摘要

A system and method for extending the reach of a data communication channel using flow control interception devices are described. The method decreases the latency-induced reduction in the data throughput and permits data transmission at subrates. The method includes transmitting a data frame from a sending device. The data frame is transmitted through the data communication channel if a flow control signal is not asserted and is buffered if the flow control signal is asserted. The buffered data frame is transmitted through the data communication channel in response the flow control signal becoming asserted state. The method also includes receiving the transmitted data frame from the data communication channel and transmitting the received data frame to a receiving device if the receiving device is available to process the data frame. If the receiving device is unavailable, the received data frame is buffered until the receiving device becomes available.
