摘要： A midplane of a communication device, includes the first connectors and the second connectors which connect with each other via high-speed traces, the first connectors arrange in parallel at one side of the midplane, the second connectors arrange in parallel at the other side of the midplane and in parallel with the first connectors. The wiring of high-speed traces between the first connectors and the second connectors can be disposed on the whole midplane, so that it avoids the high density of wiring in part of midplane, reduces the number of layers of the midplane and the complexity of design, and reduces the crosstalk in signals. And the cooling of the whole communication device can be accomplished by only one heat dissipation system, it reduces the complexity of design of the communication device. The area between each frames of the midplane is provided to allocate electrical power in the communication device with two or multiple frames, it reduces the costs of the communication device.

摘要： An access device receives a neighbor discovery protocol (NDP) packet sent from a user equipment (UE). The access device parses the NDP packet to obtain equipment information of the UE carried by the NDP packet. The access device transmits reporting message to a management server, wherein the reporting message carries the equipment information of the UE. Upon receiving a notification for identity authentication of the UE from the management server, the access device initiates an identity authentication invitation to the UE. The access device submits identity authentication information of the UE to the management server for authentication. The access device stores a first access control entry for the UE issued by the management server in its own data plane to control the UE's access to network resources after the identity authentication of the UE is permitted.

摘要： A service logic layer module receives an application message forwarded by a network device, classifies and identifies an application type of the application message, and determines a first processing operation to be performed to the application message based on an identification result. The service logic layer module receives a processing result returned from a data processing layer module, and determines a second processing operation based on the processing result. When the processing operation is an I/O processing operation for a single task, the data processing layer module controls I/O concurrency processing of the single task and returns a final processing result to the service logic layer module. When the processing operation is a data searching operation, the data processing layer module performs the data searching operation to obtain a final searching result, and returns the final searching result to the service logic layer module.
