ABSTRACT:
End-to-end data transfer between computing platforms in a transport control protocol (TCP) environment is improved by restricting which packets are stored in a receive memory of an input/output (I/O) circuit. In one embodiment, received packets are examined as to type, and the number of packets stored in the receive memory is monitored. If the number of stored packets exceeds a threshold value, then subsequently received data packets are discarded, whereas latency-sensitive priority data such as acknowledgements (ACKs) are retained in the receive memory, until the number of stored packets is reduced. Various methods, as well as application of the circuit to a system and to a machine-readable article, are also described.
