2、Data error (cyclic redundancy check).
1、cyclic redundancy check (CRC)
3、A Layer2 frame cannot be processed by a receiver until all bits have been received by the receiver and a cyclic redundancy check( CRC) has been performed.
5、Also, AAL5 calculates a 32-bit cyclic redundancy check (CRC) over the entire AAL5 protocol data unit to detect cell loss and the incorrect ordering or incorrect insertion of cells.
4、This paper puts forward three table-based software algorithms to create cyclic redundancy check(CRC) code, and analyses efficiency of the algorithms.
