Abstract: A data processing method and a server are provided. In various embodiments, a service request for invoking the meta service is received, where the service request matches metadata of the meta service. In those embodiments, the service request is converted into a cloud service request packet based on metadata of a cloud service corresponding to the meta service, where the cloud service request packet matches the metadata of the meta service. Still in those embodiments, the cloud service request packet is sent to invoke the cloud service, and a cloud service response packet is received, where the cloud service response packet is an invocation result obtained by invoking the cloud service. Also in those embodiments, the cloud service response packet is then converted into a service response that matches the metadata of the meta service and sending the service response.

Abstract: A data center network system and a signal transmission system, where the signal transmission system includes one hub device, at least two switches, multiple colored optical modules, at least two multiplexers/demultiplexers, and at least two servers. The hub device, the at least two switches, the multiple colored optical modules, the at least two multiplexers/demultiplexers, and the at least two servers form a star network topology structure.
