20140281055 | LATENCY REDUCTION FOR DIRECT MEMORY ACCESS OPERATIONS INVOLVING ADDRESS TRANSLATION - Latency reduction for direct memory access operations involving address translation is disclosed. Example methods disclosed herein to perform direct memory access (DMA) operations include initializing a ring of descriptors, the descriptors to index respective buffers for storing received data in a first memory. Such example methods also include causing prefetching of a first address translation associated with a second descriptor in the ring of descriptors to be performed after a first DMA operation is performed to store first received data in a first buffer indexed by a first descriptor in the ring of descriptors and before second received data to be stored in the first memory is received, the first address translation being associated with a second DMA operation for storing the second received data in the first memory. | 09-18-2014 |
20140281056 | LATENCY REDUCTION FOR DIRECT MEMORY ACCESS OPERATIONS INVOLVING ADDRESS TRANSLATION - Latency reduction for direct memory access operations involving address translation is disclosed. Example methods disclosed herein to perform direct memory access (DMA) operations include initializing a ring of descriptors, the descriptors to index respective buffers for storing, in a first memory, data to be transmitted. Such example methods also include causing prefetching of a first address translation associated with a second descriptor in the ring of descriptors to be performed after a first DMA operation is performed to retrieve, for transmission, first data from a first buffer indexed by a first descriptor in the ring of descriptors and before second data is determined to be ready for transmission, the first address translation being associated with a second DMA operation for retrieving the second data from the first memory. | 09-18-2014 |
20140297775 | METHOD AND SYSTEM FOR PROVIDING REMOTE DIRECT MEMORY ACCESS TO VIRTUAL MACHINES - The current document is directed to methods and systems that provide remote direct memory access (“RDMA”) to applications running within execution environments provided by guest operating systems and virtual machines above a virtualization layer. In one implementation, RDMA is accessed by application programs within virtual machines through a paravirtual interface that includes a virtual RDMA driver that transmits RDMA requests through a communications interface to a virtual RDMA endpoint in the virtualization layer. | 10-02-2014 |
20140359093 | DETECTING AND CORRECTING NETWORK INTERRUPTIONS USING NETWORK ADDRESS TRANSLATION - Embodiments provide a network address translation (NAT) service for network devices. A network connection from at least one private network device to the NAT service is received and a network connection from at least one remote device to the NAT service is received. The private network device is positioned within a private network and the remote device is positioned within a public network. A network availability of the remote device is determined. If the remote device is unavailable or a network configuration setting associated with the remote device changes, the private network device is notified and a connection reset message is transmitted to the private network device. | 12-04-2014 |
