Abstract: The present disclosure discloses a substituted graphane material with a three-dimensional structure. The substituted graphane material comprises a planar substrate with a plurality of six-membered carbon rings comprising continuous sp3 hybrids, wherein an organic molecular ring is connected to the planar substrate due to a Diels-Alder (D-A) reaction.

Abstract: A method and an apparatus for forwarding a heterogeneous protocol message, and a network switching device are provided, the method includes: receiving a network message; parsing the network message to obtain a destination address of the network message; looking up in a preset forwarding table a port corresponding to the destination address and a first protocol corresponding to the port; judging whether the first protocol matches a second protocol of the network message; performing, if not, protocol conversion on the network message in accordance with a preset conversion rule, so that the protocol type of the network message matches the port; forwarding the protocol-converted network message through the port. In the present disclosure, protocol conversion can be performed on messages from different protocol networks, so that the network switching device implements communication between different networks, and has a flexible protocol processing mode and powerful scalability.
