Abstract
A method for coalescing acknowledge packets within a server is disclosed. A Read Request queue having multiple queue pair entries is provided. Each of the queue pair entries includes a packet sequence number (PSN) field and an indicator field. In response to a receipt of a Write Request packet, an indicator field of a queue pair entry is set to indicate that an Ack packet has been queued within the queue pair entry, and a PSN of the Write Request packet is written into a PSN field of the queue pair entry. In addition, a Queue Write Pointer is maintained to point to the queue pair entry. In response to a receipt of a Read Request packet, the indicator field of the queue pair entry is set to indicate that a Read Request packet has been queued within the queue pair entry, and a PSN of the Read Request packet is written into the PSN field of the queue pair entry. Also, the Queue Write Pointer is advanced to point to a queue pair entry that is subsequent to the queue pair entry.
