摘要： Methods and systems for direct device access are disclosed. Aspects of one method may include a plurality of GOSs directly accessing a first network interface device, where the first network interface device may provide access to a network. One or more of the GOSs may be migrated to directly access a second network interface device, based on state information for each of the GOSs, where the state information may be maintained by the host. The GOSs may communicate data to a device coupled to the network by direct accessing the first and/or second network interface device. Similarly, the first and/or second network interface device may communicate data received from a device coupled to the network to one or more of the plurality of GOSs via direct access of the first and/or second network interface device.

摘要： A method for a receiver to perform processing of incoming data segments transmitted over a network by a transmitter in accordance with a transport protocol. The segments incorporate sequence values indicative of a transmission order of the segments. The method consists of receiving the data segments over the network in a reception order. Then, for each segment received in the reception order, the sequence values of the received segment and of the segments received earlier in the reception order are compared in order to assign the received segment a classification identity as an in-order or out-of-order segment.The method further includes writing the segments, in a writing order that is substantially identical to the reception order, to respective locations in an output buffer responsive to the classification identity of each segment, so that the segments in the output buffer are arranged in the transmission order.

摘要： Methods and systems for protocol offload and direct I/O with I/O sharing in a virtualized network environment are disclosed. Aspects of one method may include a plurality of GOSs sharing a single network interface circuitry, or a network interface card, (NIC) that may provide access to a network. The NIC may directly handle processing of data to be transmitted to the network and/or data received from the network for each of the GOSs without a TGOS for the GOSs handling the data to be transmitted to the network and/or data received from the network. The data may be copied directly from a buffer in the single NIC to an application buffer for one of the plurality of GOSs and/or directly from an application buffer for one of the plurality of GOSs to the buffer in the single NIC.

摘要： Certain aspects of a method and system for transparent TCP offload with a user space library are disclosed. Aspects of a method may include collecting TCP segments in a network interface card (NIC) without transferring state information to a host system. When an event occurs that terminates the collection of TCP segments, a single aggregated TCP segment based on the collected TCP segments may be generated. The aggregated TCP segment may be posted directly to a user space library, bypassing kernel processing of the aggregated TCP segment.

摘要： Methods and systems for zero copy in a virtualized network environment are disclosed. Aspects of one method may include a plurality of GOSs that share a single NIC. The NIC may switch communication to a GOS to allow that GOS access to a network via the NIC. The NIC may offload, for example, OSI layer 3, 4, and/or 5 protocol operations from a host system and/or the GOSs. The data received from, or to be transmitted to, the network by the NIC may be copied directly between the NIC's buffer and a corresponding application buffer for one of the GOSs without copying the data to a TGOS. The NIC may access the GOS buffer via a virtual address, a buffer offset, or a physical address. The virtual address and the buffer offset may be translated to a physical address.

摘要： Certain aspects of a method and system for protocol offload in paravirtualized systems may be disclosed. Exemplary aspects of the method may include preposting of application buffers to a front-end driver rather than to a NIC in a paravirtualized system. The NIC may be enabled to place the received offloaded data packets into a received data buffer corresponding to a particular GOS. A back-end driver may be enabled to acknowledge the placed offloaded data packets. The back-end driver may be enabled to forward the received data buffer corresponding to the particular GOS to the front-end driver. The front-end driver may be enabled to copy offloaded data packets from a received data buffer corresponding to a particular guest operating system (GOS) to the preposted application buffers.
