Disclosed here is a BP type architecture packet switching system that prevents delay of packet forwarding in the system itself while keeping the system configuration flexibility. Furthermore, an optical BP can be used to reduce both of the number of optical signal line parts and the manufacturing cost. In the packet switching system, a back plane (BP) board is used between a network processor and a link circuit, not between a switch and a network processor when connection is established among a switch, a network processor, and a link circuit.
