Abstract
A network in which a data packet is altered, for instance by the insertion or removal of a data portion such as a VLAN tag. The data of the data packet is read out of memory to an output means which forms the altered data packet with a new FCS portion and to a checking means which checks the integrity of the input packet using the existing FCS. The possibility for discrepancies to occur between the data supplied to the output and checking means is reduced.
