  • RDMA read destination buffers mapped onto a single representation
    Patent number: 8909727
    Abstract: A computer-implemented method, system, and article of manufacture for data communication between a requester and a responder in a remote direct memory access (RDMA) network, where each of the requester and the responder is an RDMA-enabled host of the network. The method includes: sending a request for the responder to provide data, where the request includes a mapped steering tag that is obtained by mapping a set of memory buffers of the requester onto a single representation that allows for identifying each of the memory buffers of the set; and receiving the requested data together with the mapped steering tag and assigning the data being received to the memory buffers of the set consistently with the mapping.

  • Zero copy data transmission in a software based RDMA network stack
    Patent number: 8655974
    Abstract: 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.
