    摘要： Methods and arrangements of data communications are discussed. Embodiments include transformations, code, state machines or other logic to provide data communications. An embodiment may involve receiving from a protocol stack a request for a buffer to hold data. The data may consist of all or part of a payload of a packet. The embodiment may also involve allocating space in a buffer for the data and for a header of a packet. The protocol stack may store the data in a portion of the buffer and hand down the buffer to a network device driver. The embodiment may also involve the network device driver transferring the entire packet from the buffer to a communications adapter in a single direct memory access (DMA) operation.

    摘要： A method, system, and computer usable program product for selective link aggregation in a virtualized data processing environment are provided in the illustrative embodiments. A data packet is received at a switch. An identifier associated with the data packet is determined. The identifier corresponds to a logical partition in a logical partitioned data processing system. A lookup is performed in a data structure to determine a set of ports associated with the identifier. The set of ports is retrieved from the data structure. A port is selected from the set of ports and the data packet is transmitted from the port to the logical partition.

    摘要： An approach is provided in which a local module receives a data frame initiated by a first virtual machine and has a target destination at a second virtual machine, which executes on a destination host system. The local module identifies a destination local port ID and a destination global queue pair number corresponding to the second virtual machine. In one embodiment, the destination local port ID corresponds to the destination host, but the destination global queue pair number is independent of the destination host. The local module includes the destination global queue pair number and the destination local port ID in an overlay header and encapsulates the data frame with the overlay header, which results in an encapsulated frame. In turn, the local module sends the encapsulated frame through a computer network to the second virtual machine.

    摘要： An approach is provided in which a data traffic module executing on a network interface card receives a data packet initiated by a first virtual machine with a destination at a second virtual machine. The data traffic module identifies one or more physical path translations corresponding to a logical connectivity that is independent of physical topology constraints of a physical network. In turn, the data traffic module encapsulates the data packet with the one or more physical path translations and sends the encapsulated data packet to the second virtual machine over the physical network.

    摘要： Byte utilization is improved in Remote Direct Memory Access (RDMA) communications by detecting a plurality of concurrent messages on a plurality of application sockets which are destined for the same application, client or computer, intercepting those messages and consolidating their payloads into larger payloads, and then transmitting those consolidated messages to the destination, thereby increasing the payload-to-overhead byte utilization of the RDMA transmissions. At the receiving end, multiplexing information is used to unpack the consolidated messages, and to put the original payloads into a plurality of messages which are then fed into the receiving sockets to the destination application, client or computer, thereby making the consolidation process transparent between the initiator and the target.

    摘要： An approach is provided in which a discovery system receives a migration request to move a virtual machine that executes on a first system. The discovery system identifies a first network adapter corresponding to the first system, and identifies hardware state data used by the first network adapter to process data packets generated by the virtual machine. In turn, the discovery system identifies a second network adapter that is compatible with a native format of the hardware state data, and migrates the virtual machine to a second system corresponding to the identified second network adapter.

    摘要： A data processing system stack initializes a first mbuf chain limit to a pre-set level. It receives at least one packet. The system receives at least one packet. The system returns an mbuf data structure in response to receiving at least one packet from an IP address. The system measures a health of the network connection to determine whether the network connection satisfies a first health criterion. The system reduces the mbuf chain limit to a second mbuf chain limit, responsive to the health of the network connection not satisfying the first health criterion. The system measures the health of the network connection to determine whether the network connection meets a second health criterion.
