20100057941 | Method and System for Providing Smart Offload and Upload - Provided is a system and method for performing smart offloads between computer applications module and a network interfacing device within a data communications system. The method includes receiving data requests from the computer applications module and determining whether the received data requests require offloading. The received requests are forwarded along a first data path to the network interfacing device if offloading is required. If offloading is not required, the received data requests are forwarded along a secondary data path to a host protocol stack for processing. Next, the protocol processing is performed and the processed data requests are forwarded to the network interfacing device. | 03-04-2010 |
20100115118 | SYSTEM AND METHOD FOR MANAGING MULTIPLE STACK ENVIRONMENTS - Systems and methods that manage multiple stack environments are provided. In one example, a system may include, for example, a first protocol processing stack, a second protocol processing stack and a mapper. The mapper may be coupled to the first protocol processing stack and to the second protocol processing stack. A first port number may be associated with the first protocol processing stack and a second port number may be associated with the second protocol processing stack. The mapper may store a correspondence between the first port number and the second port number. | 05-06-2010 |
20100121995 | SYSTEM AND METHOD FOR SUPPORTING TCP OUT-OF-ORDER RECEIVE DATA USING GENERIC BUFFER - A method and system for handling received out-of-order network data using generic buffers for non-posting TCP applications is disclosed. When incoming out-of-order data is received and there is no application buffer posted, a TCP data placement may notify a TCP reassembler to terminate a current generic buffer, allocate a new current generic buffer, and DMA the incoming data into the new current generic buffer. The TCP data placement may notify the TCP reassembler the starting TCP sequence number and the length of the new current generic buffer. Moreover, the TCP data placement may add entries into a TCP out-of-order table when the incoming data creates a new disjoint area. The TCP data placement may adjust an existing disjoint area to reflect any updates. When a TCP application allocates or posts a buffer, then the TCP reassembler may copy data from a linked list of generic buffers into posted buffers. | 05-13-2010 |
20100262859 | SYSTEM AND METHOD FOR FAULT TOLERANT TCP OFFLOAD - Systems and methods that provide fault tolerant transmission control protocol (TCP) offloading are provided. In one example, a method that provides fault tolerant TCP offloading is provided. The method may include one or more of the following steps: receiving TCP segment via a TCP offload engine (TOE); calculating a TCP sequence number; writing a receive sequence record based upon at least the calculated TCP sequence number to a TCP sequence update queue in a host; and updating a first host variable with a value from the written receive sequence record. | 10-14-2010 |
20100306521 | METHOD AND SYSTEM FOR ISCSI BOOT IN WHICH AN ISCSI CLIENT LOADS BOOT CODE FROM A HOST BUS ADAPTER AND/OR NETWORK INTERFACE CARD - Certain aspects of a method for iSCSI boot may include loading boot BIOS code from a host bus adapter or a network interface controller (NIC) by an iSCSI client device. A connection may be established to an iSCSI target by the iSCSI client device after loading the boot BIOS code. The boot BIOS code may be chained to at least one interrupt handler over iSCSI protocol. An operating system may be remotely booted from the iSCSI target by the iSCSI client device based on chaining the interrupt handler. An Internet protocol (IP) address and/or location of the iSCSI target may be received. At least one iSCSI connection may be initiated to the iSCSI target based on chaining at least one interrupt handler. The iSCSI target may be booted in real mode if at least one master boot record is located in the memory. | 12-02-2010 |
20110185089 | Method and System for Supporting Hardware Acceleration for iSCSI Read and Write Operations and iSCSI Chimney - Certain aspects of a method and system for supporting hardware acceleration for iSCSI read and write operations via a TCP offload engine may comprise pre-registering at least one buffer with hardware. An iSCSI command may be received from an initiator. An initiator test tag value, a data sequence value and/or a buffer offset value of an iSCSI buffer may be compared with the pre-registered buffer. Data may be fetched from the pre-registered buffer based on comparing the initiator test tag value, the data sequence value and/or the buffer offset value of the iSCSI buffer with the pre-registered buffer. The fetched data may be zero copied from the pre-registered buffer to the initiator. | 07-28-2011 |
20110307577 | METHOD AND SYSTEM FOR TRANSMIT SCHEDULING FOR MULTI-LAYER NETWORK INTERFACE CONTROLLER (NIC) OPERATION - A method for processing network data includes collecting by a network interface controller (NIC), a plurality of transmit (TX) buffer indicators into a plurality of priority lists of connections. Each of the plurality of TX buffer indicators identifies transmit-ready data located externally to the NIC and not previously received by the NIC. One or more of the plurality of TX buffer indicators may be selected. The identified transmit-ready data may be retrieved into the NIC based on the selected one or more of the plurality of TX buffer indicators. At least a portion of the identified transmit-ready data may be transmitted. Each of the plurality of priority lists may be generated based on a particular connection priority characteristic and a particular connection type. The identified transmit-ready data may be associated with the same connection priority characteristic and the same connection type. | 12-15-2011 |
20110314171 | SYSTEM AND METHOD FOR PROVIDING POOLING OR DYNAMIC ALLOCATION OF CONNECTION CONTEXT DATA - A method for processing of packetized data is disclosed and includes allocating a plurality of partitions of a single context memory for handling data for a corresponding plurality of network protocol connections. Data for at least one of the plurality of network protocol connections may be processed utilizing a corresponding at least one of the plurality of partitions of the single context memory. The at least one of the plurality of partitions of the single context memory may be de-allocated, when the corresponding at least one of the plurality of network protocol connections is terminated. The data for the at least one of the plurality of network protocol connections may be received. The data may be associated with a single network protocol or with a plurality of network protocols. The data for the at least one of the plurality of network protocol connections includes context data. | 12-22-2011 |
