This application discloses an optical backplane system, which includes a first upper-level optical interconnection module, a first lower-level optical interconnection module, and a second lower-level optical interconnection module. The first upper-level optical interconnection module includes M1 first interfaces and N1 second interfaces in connection relationships. The first lower-level optical interconnection module includes L1 third interfaces and K1 fourth interfaces in connection relationships. The second lower-level optical interconnection module includes L2 third interfaces and K2 fourth interfaces in connection relationships. The first upper-level optical interconnection module is connected to one of the L1 third interfaces of the first lower-level optical interconnection module by using one of the N1 second interfaces. The first upper-level optical interconnection module is connected to one of the L2 third interfaces of the second lower-level optical interconnection module by using another one of the N1 second interfaces.

Optical backplane system, switching system, and switching system upgrade method

The present disclosure relates to registration methods and devices. One example method includes obtaining, by a line card, line card information of the line card, the line card comprising a fabric interface chip optically interconnected to a switch fabric chip in at least one switch fabric card by using an optical fiber, and sending, by the line card, the line card information to the at least one switch fabric card through an optical interconnect path. The at least one switch fabric card registers the line card based on the line card information.

Board registration method, board, and forwarding device

A cluster router includes at least one control apparatus and at least two forwarding apparatuses. The control apparatus is connected to the forwarding apparatuses, and the forwarding apparatuses are connected with each other. The control apparatus is configured to generate a routing table of each forwarding apparatus and a packet processing information conversion table of each forwarding apparatus. The forwarding apparatus is configured to receive the routing table of the forwarding apparatus and the packet processing information conversion table of the forwarding apparatus, and execute data exchange between the forwarding apparatuses according to the routing table and the packet processing information conversion table.
