摘要： Packet switch operating methods and packet switches, using primary control circuitry of the packet switch, receive a request to perform a transaction. In response to the receiving the request, the primary control circuitry forwards the request to backup control circuitry of the packet switch. Subsequent to forwarding the request, the primary control circuitry performs the transaction by modifying a plurality of first data objects stored in a memory of the primary control circuitry. The packet switch operating methods and packet switches, using the primary control circuitry, inform the backup control circuitry that the primary control circuitry has performed the transaction and, in response to the informing, the backup control circuitry performs the transaction by modifying a plurality of second data objects stored in a memory of the backup control circuitry. The first data objects correspond to the second data objects.
