摘要： A switching process includes an SRAM/CAM storing registration data including a forwarding database used for packet-forwarding and a DRAM storing packet data. The registration data including the forwarding database of the SRAM/CAM for packet-forwarding is stored into the DRAM as a copy of the registration data, and the registration data of the DRAM is used to refresh the registration data of the SRAM/CAM for a predetermined time interval. A data error in the SRAM/CAM caused by a soft-error is rewritten to normal data by periodical refreshing so that data is guaranteed with relatively low cost and the reliability of the network apparatus is improved.
