Abstract: A routing node includes: at least one optical buffer, a switching node, and at least one transmission waveguide, where an output end of each optical buffer is connected to an input end of the switching node; each transmission waveguide is connected to an output end of the switching node. The optical buffer is configured to parse a received optical signal to obtain an identifier of a destination routing node, and send the identifier to the switching node. The switching node determines whether an output port required by the destination routing node is in an idle state or a busy state; and control the optical buffer to store the optical signal if the output port is in a busy state; or send the optical signal to the destination routing node if the output port is in an idle state.

Abstract: An interconnection system, an apparatus, and a data transmission method. In the interconnection system, to-be-transmitted data is converted into a data packet in an optical signal form for transmission, and a control packet corresponding to the data packet is transmitted in an electrical signal form and includes routing information of the data packet. When the control packet passes through a switching node, the switching node directly determines, according to the routing information in the control packet, a neighboring node that serves as a next hop, and opens, in the switching node, an optical path used to transmit the data packet. Because no optical-to-electrical or electrical-to-optical conversion needs to be performed on the control packet and the data packet during an entire transmission procedure, problems of an extra delay and power consumption caused by electrical-optical-electrical conversion can be reduced, thereby improving data transmission efficiency.
