  • TCP-splitter: reliable packet monitoring methods and apparatus for high speed networks
    Patent number: 7711844
    Abstract: A method for obtaining data while facilitating keeping a minimum amount of state is provided. The method includes receiving at a first device an Internet Protocol (IP) frame sent from a second device to a third device wherein the first device is in a flow path between the second and third devices, the first device including at least one of an Application Specific Integrated Circuit (ASIC) and a Field Programmable Gate Array FPGA. The method also includes removing an embedded stream-oriented protocol frame including a header and a data packet from the received IP frame with at least one of the ASIC and the FPGA, and determining a validity of a checksum of the removed steam-oriented protocol header.
    Type: Grant

  • Reliable packet monitoring methods and apparatus for high speed networks
    Publication number: 20040049596
    Abstract: A method for controlling traffic on a network includes monitoring a data stream, determining a particular byte offset within the monitored stream at which to block flow of the stream, and blocking flow of the data stream at the determined byte offset.
