Abstract
A method and apparatus are provided for checksum verification with receive packet processing for communications over a data communications network. First a data communications connection is identified. Responsive to an identified data communications connection, a start of data packet is identified. Then a header checksum is calculated. A protocol checksum including a protocol pseudo header and data is calculated. An embedded processor structure is used for tracking packet state and running CRC calculations across received packets, and performing full checksum verification.
