摘要： Certain aspects of a method and system for transparent transmission control protocol (TCP) offload with best effort direct placement of incoming traffic are disclosed. Aspects of a method may include collecting TCP segments in a network interface card (NIC) processor without transferring state information to a host processor every time a TCP segment is received. When an event occurs that terminates the collection of TCP segments, the NIC processor may generate a new aggregated TCP segment based on the collected TCP segments. If a placement sequence number corresponding to the generated new TCP segment for the particular network flow is received before the TCP segment is received, the generated new TCP segment may be transferred directly from the memory to the user buffer instead of transferring the data to a kernel buffer, which would require further copy by the host stack from kernel buffer to user buffer.
摘要翻译：公开了透明传输控制协议（TCP）卸载的方法和系统的某些方面，尽力而为直接布置入局业务。方法的各方面可以包括在网络接口卡（NIC）处理器中收集TCP片段，而每当接收到TCP片段时都不向主处理器传送状态信息。当发生终止TCP段的收集的事件时，NIC处理器可以基于收集的TCP段生成新的聚合TCP段。如果在接收到TCP段之前接收到对应于特定网络流的生成的新TCP段的布置序列号，则所生成的新TCP段可以直接从存储器传送到用户缓冲区，而不是将数据传送到内核缓冲区，这将需要主机栈从内核缓冲区进一步复制到用户缓冲区。

摘要： Certain aspects of a method and system for transparent transmission control protocol (TCP) offload with transmit and receive coupling are disclosed. Aspects of a method may include collecting at least one received TCP segment for a determined network flow via a network interface card (NIC) processor. The state information for the received TCP segment and state information for transmitted TCP segments for the determined network flow may be stored at the NIC without transferring state information for the received TCP segment and the state information for the transmitted TCP segments to a host system communicatively coupled to the NIC. A new TCP segment comprising the collected TCP segments may be generated after a termination event occurs. The generated new TCP segment, new state information for the generated new TCP segment, and the state information for the transmitted TCP segments may be communicated to the host system for TCP offload.

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： Methods and systems for a plurality of physical layers for network connection may include coupling a MAC to one of a plurality of PHYs. The coupling to a specific PHY may be based on auto-detection of network activity, or network devices, via the PHYs. Also, one of the PHYs may be coupled to the MAC as a power-up default. The PHYs may be coupled to a same network, by, for example, cables. A first cable to a first PHY may couple it to a first network switch and a second cable to a second PHY may couple it to a second network switch. The first network switch may be rated to handle, for example, a greater data rate than the second network switch. The first cable may not be able to be used as a cable for the second PHY, and vice versa.

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.
