Abstract
Link-based flow control requires each link transmitter to retain packets until such time as they are acknowledged by the link receiver. Depending on the type of acknowledge, the transmitter will then either retry or de-allocate the packets. To improve throughput, the present invention includes an optimistic transmitter, which transmits packets without knowing the state of the receiver buffer. By so doing, the present invention improves the latency caused by delays in transit time between nodes. Furthermore, single acknowledgments are used to indicate successful receipt of multiple packets. Single negative acknowledgments are used to indicate successful receipt of all data between a last acknowledged data packet and a packet associated with the negative acknowledgment, which was received with errors.
