摘要： A method includes obtaining, by a first network device comprising a processor, characteristic information from an encrypted packet received from a second network device based on a determination that the first network device cannot decrypt the encrypted packet. The first network device is free from having an internet protocol security (IPsec) security association (SA), and the second network device has the IPsec SA. The method also includes generating, by the first network device, generating an informational exchange packet when the first network device obtains, based on the characteristic information, an internet key exchange (IKE) SA corresponding to the characteristic information. The informational exchange packet instructs the second network device to delete the IPsec SA on the second network device. The method further includes sending, by the first network device, the informational exchange packet to the second network device.

摘要： A data visualization method and apparatus, where the method includes displaying a first density distribution diagram on a first map, where the first density distribution diagram represents density distribution, in a region, of source locations of flow events whose destinations are located in a target reference region, and displaying a second density distribution diagram on a second map, where the second density distribution diagram represents density distribution, in a region, of destinations of flow events whose source locations are located in the target reference region. Hence, bidirectional density distribution associated with each other using the target reference region are displayed on two maps in a linked manner, thereby implementing visualization of bidirectional density distribution data.

摘要： Example methods and apparatus for generating a heatmap are described. One example method includes dividing a current display region of an original image on a screen into cells. The basic heat of a heat point region in each cell is calculated according to statistics and a heat weight for generating a heatmap this time, and diffusion heat to which each pixel in the current display region is subject is calculated according to the basic heat of the heat point region in the cell. The total heat of each pixel in the current display region is obtained, and a color corresponding to the total heat of each pixel in the current display region is presented in the current display region of the original image according to a preset heat presentation correspondence to obtain a heatmap of the current display region.

摘要： The present disclosure provides a data visualization method and apparatus. The method includes: displaying a distribution curve diagram by using a display device, where the distribution curve diagram is used to represent time-based distribution of multiple pieces of spatial-temporal data, and the distribution curve diagram includes a timeline, a curve changing with the timeline, and an irregular region enclosed by the curve; and displaying a tree map in the irregular region by using the display device, where the tree map divides the irregular region into m sub-regions that are in a one-to-one correspondence with m regions, and an area of each of the m sub-regions is used to indicate an amount of spatial-temporal data distributed in a region corresponding to each sub-region. The present disclosure implements visualization of spatial-temporal data by using the tree map.

摘要： A method and apparatus for presenting spatial-temporal data, which relate to the field of information processing technologies, are presented. When querying data according to a user query request, the apparatus for presenting spatial-temporal data finds various types of data that correspond to a spatial condition and that are included in the data that the user query request requests to query, where the various types of data include regional data and variation data of a preset feature, and presents, in a graph, both the regional data and the variation data of the preset feature. In this way, various types of data are found during data query, so that spatial-temporal data is presented in a centralized way in a specific manner, and spatial-temporal data dynamics may be further presented and hence a user intuitively views an association relationship between spatial data and temporal data, which facilitates further analysis of the data.
