Abstract: 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.

Abstract: A method for decoding a received word, including calculating a syndrome of the received word as a plurality of binary element vectors, generating respective logarithms of the binary element vectors, and determining, in response to the logarithms, an indication of a position of an erroneous bit in the received word.

Abstract: Cache apparatus, including first and second cache memories, coupled to receive and hold context information from an external memory with respect to tasks, each task activated by one or more activating events, so that the context information is available for access by a processor in performing the tasks. The cache apparatus further includes a mapper, which is coupled to receive a classification of the tasks as fast and slow tasks. The mapper is adapted, upon receipt of one of the activating events for one of the fast tasks to be performed by the processor, to cause the context information with respect thereto to be received in the first cache memory, and upon receipt of one of the activating events for one of the slow tasks to be performed by the processor, to cause the context information with respect thereto to be received in the second cache memory.

Abstract: A microprocessor, including a plurality of registers and an instruction execution module which is adapted to process a sequence of conditional tests.

Abstract: 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.

Abstract: Apparatus for receiving a sequence of Transmission Control Protocol (TCP) segments, including a parsing machine which is adapted to parse at least one TCP segment so as to recover an Internet Small Computer Systems Interface Protocol Data Unit (iSCSI PDU), the PDU including a header and at least part of a payload. The apparatus further includes at least one analysis machine which is adapted to receive and evaluate the header and to receive and route the at least part of the payload for the iSCSI PDU, the parsing machine and the at least one analysis machine operating substantially autonomously.

Abstract: A method for processing a datagram, including receiving an initial fragment of the datagram over a communication link and classifying in an initial classification the initial fragment as a first fragment, a middle fragment, or a last fragment of the datagram. The method further includes receiving one or more subsequent fragments over the communication link, following the initial fragment, and classifying each of the one or more subsequent fragments in respective subsequent classifications so as to find among the subsequent fragments at least one of the first fragment, the middle fragment, and the last fragment of the datagram.
