Reducing network latency

摘要

A method of transmitting data for use at a data processing system and network interface device, the data processing system being coupled to a network by the network interface device, the method comprising: forming a message template in accordance with a predetermined set of network protocols, the message template including at least in part one or more protocol headers; forming an application layer message in one or more parts; updating the message template with the parts of the application layer message; processing the message template in accordance with the predetermined set of network protocols so as to complete the protocol headers; and causing the network interface device to transmit the completed message over the network.

1. A method of transmitting data for use at a data processing system supporting an application, an application programming interface and a network protocol stack, the data processing system being coupled to a network by a network interface device, the method comprising:
forming by the application one or more parts of a message for transmission; causing by the application programming interface inclusion of said one or more parts of the message for transmission in the message, and one or more protocol headers, in accordance with a predetermined set of protocols, for the message for transmission; on completion of the message for transmission, process the message in accordance with the predetermined set of protocols to complete the protocol headers; causing the network interface device to transmit the completed message over the network; and wherein the network protocol stack comprises at least two parts: a first part supported at the data processing system and a second part supported at the network interface device; the first part being configured to perform the step of forming at least in part one or more protocol headers of the message for transmission; and the second part being configured to perform the step of processing the message to complete the protocol headers.
