  • TCP retransmission and exception processing in high speed, low memory hardware devices
    Patent number: 7554917
    Abstract: A method and system for the retransmission of TCP segments in a high speed, low memory TOE device or processor system uses one or more selective context duplication (SCD) TCP/IP connections to provide retransmission assistance to an original TCP/IP connection. SCD connections are used only to retransmit TCP segments on behalf of the system. The original connection and SCD connections are linked together and managed using a TCP state engine in such a way that the original connection receives and processes acknowledgements (ACKs) and selective acknowledgements (SACKs) transmitted back to the system. In many applications, the original connection is able to continue transmitting even while the SCD connection is retransmitting.

  • Interface for distributed processing of SCSI tasks
    Patent number: 6952743
    Abstract: The SCSI control block interface provides for distributed processing of storage commands that provides transports and processing blocks the ability to interconnect with each other independent of the underlying transport or hardware architecture. The interface receives a SCSI control block from a transport and determines a storage command associated with the SCSI control block. Based upon the storage command, a particular processor that processes the storage command is determined. The SCSI control block is routed to the appropriate processor for processing. After processing, the SCB is routed to a transport for delivery.
