Abstract
A method is provided for transmitting packets of a packet stream in real-time. The method includes sequentially writing packets in a retry buffer of a transmitting agent, the retry buffer including multiple contexts; sequentially transmitting the packets written in the retry buffer to a receiving agent, while continuing to sequentially write additional packets the retry buffer; receiving acknowledgements from the receiving agent when the receiving agent has successfully received the transmitted packets, while continuing to sequentially transmit the packets written in the retry buffer to the receive agent; receiving a retry request from the receiving agent when the receiving agent has not successfully received a transmitted packet; and retransmitting packets from the retry buffer to the receiving agent beginning with the transmitted packet not successfully received by the receiving agent, which resulted in the retry request, while continuing to sequentially write additional packets received from the transmitting agent in the retry buffer.
