Abstract: Disclosed are methods that couple effective nesting of fabric, as part of a textile cutting process, in which designs and/or graphic elements are directly printed on the nested elements, instead of on the entire textile sheet. Embodiments of the invention can address issues of waste and redundant printing, such as by starting with a blank textile roll, and printing only in the geometry areas of the patterns. Embodiments of the invention can increase fabric yield, because there are no constraints between the pattern geometries and the textile sheet print.

Abstract: A method for processing network information may include performing by one or more processors and/or circuits integrated within a single chip, classifying a header portion of a received packet based on connection context information within the received packet. The connection context information may be acquired by the single chip from a memory external to the single chip. The connection context information for the received packet may be updated based on the classifying. At least a payload portion of the received packet may be communicated to a destination, based on the updated connection context information. The classifying, updating and communicating may be performed asynchronously. The header portion of the received packet may be parsed and/or validated. The connection context information of the received packet may be evaluated.

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. Responsive to the initial and the one or more subsequent classifications, a determination is made whether the datagram is completely constituted by the initial fragment and no more than two of the subsequent fragments. The datagram is reassembled responsive to the determination.

Abstract: A method for communication is disclosed and may include, in a network interface device, parsing a portion of a TCP segment into one or more portions of Internet Small Computer Systems Interface (iSCSI) Protocol Data Units (PDUs). A header and/or a payload for one or more of the parsed iSCSI PDUs may be recovered. Concurrent with parsing of a remaining portion of the TCP segment to recover a remaining portion of PDUs, the recovered header may be evaluated and/or the recovered payload may be routed external to the network interface device for processing. The evaluating and the routing may occur independently of the parsing within the network interface device. Respective separate physical processors may be used for the parsing and the recovering. The respective separate processors for recovering may be used for the evaluating and the routing.

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. 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.

Abstract: A transport protocol receiver for receiving a packet from a network, the packet having a header, payload, and connection context.

Abstract: A data transceiver includes a transmitter, which generates datagrams for transmission to a peer over a network in accordance with a reliable transport protocol, so as to transmit the datagrams substantially continuously from a starting datagram through a final datagram in a current transmission window. A receiver is coupled to receive acknowledgments from the peer of the datagrams that have reached the peer over the network. A synchronization interface receives the acknowledgments from the receiver and, responsive thereto, redetermines the starting datagram and informs the transmitter of the redetermined starting datagram, causing the transmitter to redetermine the final datagram in the current transmission window substantially without interrupting the transmission of the datagrams.

Abstract: A method for routing a data flow from a source node to a destination node among a plurality of nodes mutually linked in a ring by segments of a communication network, configured so that the data flow can traverse the ring in either of first and second, mutually-opposing directions of communication. The method includes maintaining at each of the nodes a record of respective levels of use of a network resource on the segments in the ring for both the first and second directions of communication. Responsive to the respective levels of use, one of the directions is selected at the source node, in which to route the data flow to the destination node. A notification is sent from the source node to the other nodes in the ring of an additional allocation of the resource required by the source node in order to convey the data flow to the destination node in the selected direction on the segments in the ring.
