Method and apparatus for fast checking the frame check sequence of a segmented message

摘要: A process and an apparatus to calculate the FCS (Frame Check Sequence) error checking code of a message sent over connection segmented into finite number packets in fixed size network. The is implemented adapter cards ATM network access nodes (2, 4) located at boundary These nodes, when supporting AAL5 type connections, reassemble messages which have been entry cell payloads for data integrity checking. invention starts each reception with calculation partial (10) performed parallel control block fetching phase (40); these 2 operations allow during processing time connections established medium high speed lines.
