Abstract: The disclosure provides a method for detecting and defending a Distributed Denial of Service attack in an SDN environment. The method includes: building data messages acquired as feature messages by a proxy module; sending the feature messages to a pre-built detection model to obtain a detection result; making a decision instruction based on the detection result; and performing control operations by the proxy module based on the decision instruction.

Abstract: Disclosed in the invention is an emergency message transmission method based on D2D communication in IoV. Firstly, priority indexes are established for a set of vehicles within a safety range of a certain vehicle, and D2D connection pairs are established in ascending order of the priority indexes to transmit messages; and then, distance prediction is performed on the set of vehicles outside the safety range, priority indexes are established according to predicted distances, and D2D connection pairs are established in ascending order of the priority indexes to transmit messages. If same priority indexes appear, vehicles on the same lane are selected first. The invention implements timely transmission of safety warning information on basis of D2D communication, and performs safety warning, thereby solving the technical problem of inability to transmit safety information in time, and improving transmission performance of traffic messages. Therefore, the invention has high reliability and real-time properties.

Abstract: A vehicle clustering method includes: acquiring vehicle dynamic information, the vehicle dynamic information including vehicle positions and vehicle speeds; clustering vehicles based on the vehicle dynamic information; calculating, based on the vehicle dynamic information, a link reliability and a link stability of the vehicles in a cluster; calculating, based on the link reliability and the link stability, a selection priority index for a cluster head; and selecting a vehicle with a largest selection priority index in the cluster as a cluster head.

Abstract: A container image management system for distributed clusters, the system including at least one master node and at least one worker node. The at least one master node includes a container image database, a request input module and a container image management module. The container image management module is responsive when the container image management module establishes the connection to the container image database, then it is configured to perform a read/write operation on the container image database. The container image database is a distributed database configured to store node information of the at least one master node and the at least one worker node in the container image management system. The request input module is configured to receive request content including a request destination and command execution content. The command execution content includes an execution operation field and an executed container image list.
