Abstract
A system and method for checking for data transmission errors in a network includes a cyclic redundancy code (CRC) generator and a processing device. The CRC generator receives a stream of data representing cells in a packet of data. The CRC generator generates a CRC value for each cell and transmits the CRC value to a processing device. The processing device combines the cell CRC values to generate a CRC for a packet of data. The processing device then compares the packet CRC to an expected value to determine whether an error occurred in the data transmission.
