Multiplex communications – Fault recovery – Bypass an inoperative switch or inoperative element of a...
When any communication port receives a packet from a network, it transmits the packet to a relay processing section. The relay processing section identifies a relay processing section of a transfer destination according to destination information included in the packet to transmit the packet to a packet switch section. When the relay processing section of the transfer destination is a working relay processing section, the packet switch section transfers the packet to the working relay processing section and a protection relay processing section.
