摘要
A method, apparatus, and system for implementing a link layer retry protocol utilizing an implicit acknowledgment (ACK) are disclosed. The peer link interface is configured to allow robust and error-free delivery of link-layer packets using an implicit ACK, and to retransmit packets for which an error is detected so that link control data is successfully received or data transmission over the link Is prevented. Together with the transmission packet, the reliable packet is sequentially copied to the slot in the replay buffer. Each link interface traces the slot in which each reliable packet is buffered, and in response to detection of an error, a retry request is sent to the sender to cause it to retransmit the erroneous packet. A copy of the previously erroneously buffered packet is retrieved from the replay buffer and retransmitted. Using the link round trip detection mechanism, the absence of a retry request by the time the replay buffer has returned to the slot of a reliable packet (plus the number of additional transmission cycles if applicable) Lt; RTI ID = 0.0 ACK. / RTI
