Abstract
A network switch includes a receive port configured to receive data and two or more parallel first paths each configured to receive a first copy of the data, perform a check on the first copy, and generate a protection for the first copy. One or more first voter elements are configured to receive second copies of the data and to crosscheck the second copies. A processing section is configured to process one or more of the second copies. Two or more parallel second paths are each configured to receive a third copy of the data and perform multiple checks on the third copy including a check based on the protection. One or more second voter elements are configured to receive fourth copies of the data and to crosscheck the fourth copies. A send port is configured to send one or more of the fourth copies to a next network element.
