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. The method also includes dropping the IP frame when the checksum is invalid, supplying a client application with data from the removed protocol frame when the checksum is valid, and sending an IP frame including the removed stream-oriented protocol frame to the third device from the first device when the checksum is valid.
