Abstract: A packet forwarding method and apparatus pertaining to the field of communications technologies are disclosed. The method includes: determining whether a current to-be-sent target packet is a header packet or a following packet in a burst sequence; when the target packet is the following packet in the burst sequence, obtaining port information of an egress port used to send the burst sequence, where the port information of the egress port is determined and stored when the header packet in the burst sequence is sent, and the burst sequence is a sequence including a plurality of packets that belong to a same service flow; and sending the target packet through the obtained egress port.

Abstract: 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.

Abstract: 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.
