ZERO COPY DATA TRANSMISSION IN A SOFTWARE BASED RDMA NETWORK STACK

摘要

A method for data transmission on a device without intermediate buffering is provided. An application request is received to transmit data from the device to a second device over a network. The data from application memory is formatted for transmitting to the second device. The data are transmitted from the device to the second device without intermediate buffering. A send state is retrieved. The send state is compared to expected send state. If the send state meets the expected send state, a completion of the data transmit request is generated.
