Receiving the equipment information of the server through the acquisition module;
And determining the topological relation according to the equipment information.
13. The apparatus of claim 9 or 10, wherein the apparatus is a virtual switch.
14. An apparatus for transmitting a message, the apparatus comprising:
the access switch is used for acquiring a second message which accords with a second transmission protocol from the access switch, wherein the access switch does not support the second transmission protocol, and the access switch is configured with a transparent transmission command;
The generating module is used for generating a first message which accords with a first transmission protocol according to the second message acquired by the acquiring module;
And the sending module is used for sending the first message generated by the generating module.
15. The apparatus of claim 14, wherein the first transport protocol is a Virtual Local Area Network (VLAN) transport protocol and the second transport protocol is a virtual extensible local area network (VxLAN) transport protocol.
16. the apparatus of claim 14 or 15, wherein the apparatus is a virtual switch.
