    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: Embodiments of the present invention disclose a network selection method, an apparatus and a base station. The method includes: determining each of networks satisfying requirements of a user when the user initiates a service or transmits a service; estimating an average energy efficiency of a system during service transmission after the user selects to access each of the networks; selecting a network which can make the average energy efficiency of the system reach a preset threshold value to serve the user. Embodiments of the present invention solve a problem in the prior art that, because no consideration is given to network energy consumption in the network selection, system energy efficiency is reduced. Through comprehensive consideration of network energy efficiency and system energy efficiency, the need for energy saving and consumption reduction is met.

    Abstract: The present disclosure discloses a method and apparatus for processing network protocol stack data. The method includes: extracting, from a to-be-processed data packet, an identifier used to indicate a data flow to which the to-be-processed data packet belongs; when a pre-generated rule matching table includes the identifier, processing, according to a protocol-stack layer jump processing policy that is corresponding to the identifier and that is in the rule matching table, the to-be-processed data packet on a target layer indicated by the protocol-stack layer jump processing policy. By using the method and apparatus in the present disclosure, unnecessary processing may not be performed on some data packets that do not need to be processed on all protocol-stack layers, so as to reduce or even avoid unnecessary consumption of computing resources and transmission resources.
