摘要： A method for communication includes inputting from a host processor to a network interface device a sequence of work requests indicative of operations to be carried out by the network interface device with respect to a plurality of the connections. The device looks ahead through the sequence in order to identify at least first and second operations that are to be carried out with respect to one of the connections in response to first and second work requests, respectively, wherein the second work request does not immediately follow the first work request in the sequence. The device loads the context data for the one of the connections from a host memory into a context cache, and performs at least the first and second operations sequentially while the context data are held in the cache.

摘要： Certain aspects of a method and system for transparent transmission control protocol (TCP) offload with per flow estimation of far end transmit window are disclosed. Aspects of a method may include storing at a network interface card (NIC) processor state information for a received TCP segment and state information for transmitted TCP segments for a determined network flow without transferring state information for the received TCP segment to a host system communicatively coupled to the NIC. The generation of a new TCP segment comprising the collected received TCP segments may be controlled based on the occurrence of a termination event and a transmit window size. The period of time for aggregation of received TCP segments may be calculated based on the sequence numbers of the next expected TCP segment and the next received acknowledgement packet.

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： Certain aspects of a method and system for transparent transmission control protocol (TCP) offload 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 system. The collected TCP segments may be buffered in a coalescer. The coalescer may verify that the network flow associated with the collected TCP segments has an entry in a flow lookup table (FLT). When the FLT is full, the coalescer may close a current entry and assign the network flow to the available entry. The coalescer may also update information in the FLT. When an event occurs that terminates the collection of TCP segments, the coalescer may generate a single aggregated TCP segment based on the collected TCP segments. The aggregated TCP segment and state information may be communicated to the host system for processing.
