Abstract: This invention discloses a three-dimensional imaging radar system and method based on a plurality of times of integral. The system includes an LED light source, an optical band-pass filter, an image sensor, an electronic shutter, a data processor, and a display terminal. The LED light source generates a series of light pulse trains, and when the light pulse trains illuminate an object, the object reflects the light in succession. The reflected light is sensed by the image sensor through the optical band-pass filter, to form an image on the image sensor. The image sensor performs exposure imaging three times in succession for the reflected light of the same pulse under the action of the electronic shutter. The data processor analyzes the three images to obtain contour information and distance information about the object. Finally, the display terminal displays results.

Abstract: The present invention discloses a method and an apparatus for configuring a network policy of a virtual network. The method includes: receiving, by a server, a network policy message sent by a virtual machine management center and used for creating a virtual network, where the network policy message for creating a virtual network includes a virtual network identification (VNID) of a virtual network to be created and network policy configuration information corresponding to the virtual network to be created; and sending, by the server, a network policy synchronization message to a network device, where the network policy synchronization message includes the VNID of the virtual network to be created and the network policy configuration information corresponding to the virtual network to be created. Consequently, processing overheads can be reduced.

The method includes receiving a virtual machine parameter migration message at a not-running stage of a virtual machine, where the virtual machine parameter migration message is used to cause an upstream network device of the virtual machine to migrate virtual machine parameters of the virtual machine at the not-running stage of the virtual machine, and the virtual machine parameter migration message includes an identifier of the virtual machine. The present invention may implement migration of the virtual machine parameters correctly and solve a service interruption problem in virtual machine migration.

Abstract: A method, an apparatus, and a system for network address translation related to the field of communications technologies. A NAT control apparatus receives a network address migration message after a first data center migrates a NAT mapping entry corresponding to a migrated virtual machine VM to a second data center, verifies the network address migration message, and updates home information of the NAT mapping entry in a network address mapping table from the first data center to the second data center according to the network address migration message. In this way, NAT address resources in each data center can be properly planned, and a release attack problem caused by a fact that applying and using of a VM are not performed in a same data center can be solved.

Abstract: A method implemented by a network component is provided. The method includes receiving a Virtual Station Interface (VSI) Discovery Protocol (VDP) request from an Edge Virtual Bridging (EVB) station and transmitting, to the EVB station, a VDP Response in response to the request. The VDP Response includes a VDP Type-Length-Value (TLV) having a Filter Information field. The Filter Information field is configured to specify a Priority Code Point (PCP) value associated with one or more Virtual Local Area Network (VLAN) Identifier (VID) values carried by the VDP Response. The PCP value is carried in a PCP field and adopted by the EVB station as a default PCP value associated with the VSI and at least one VID. The Filter Information field further contains a PCP Significant (PS) field associated with each PCP field, and wherein the PS field indicates whether the PCP field carries the PCP value.
