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.

摘要： A controller of a virtual switch system receives an uplink packet forwarded by a SDN switch hosted on a server from a VM (virtual machine) hosted on the server. The controller determines an outgoing interface from at least two uplink interfaces on the SDN switch respectively corresponding to aggregated member ports of a physical switch by using an aggregation algorithm according to the uplink packet. The controller generates a first flow table entry and sends the first flow table entry to the SDN switch, wherein the first flow table entry is to instruct the SDN switch to forward a received uplink packet to the physical switch through the outgoing interface.

摘要： A label switching router (LSR) and a method of switching data traffic to a predefined backup traffic path by the LSR in an MPLS (multi-protocol label switching) network. The LSR, upon detection of failure of a protected path during an LDP session, maintains an LDP session and forwards data traffic via the backup traffic path according to a forwarding table. The forwarding table contains logical output interface information including an outgoing label, a logical output interface, and the next hop of the predefined backup path.
