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.
