Patent number: 11140197Abstract: Provided are a DDoS attack detection method and apparatus. The method comprises: acquiring network traffic of a target moment within a first period by sampling, then querying a traffic period change curve acquired in advance, determining predicted traffic corresponding to the target moment, and confirming a DDoS attack if the network traffic acquired by sampling is larger than the determined predicted traffic. The traffic period change curve is used for indicating a period change law of the predicted traffic, so that before DDoS attack detection is performed at each target moment, it only needs to determine the predicted traffic corresponding to the target moment according to the traffic period change curve without calculating the predicted traffic according to massive historical traffic data before each DDoS attack detection; and the calculation volume is reduced.Type: GrantFiled: February 22, 2017Date of Patent: October 5, 2021Assignee: NSFOCUS INFORMATION TECHNOLOGY CO., LTD.Inventors: Hanbing Chen, Bin Zheng, Kun He

Patent number: 9607440Abstract: In one aspect, an HMD is disclosed that provides a technique for generating a composite image representing the view of a wearer of the HMD. The HMD may include a display and a front-facing camera, and may be configured to perform certain functions. For instance, the HMD may be configured to make a determination that a trigger event occurred and responsively both generate a first image that is indicative of content displayed on the display, and cause the camera to capture a second image that is indicative of a real-world field-of-view associated with the HMD. Further, the HMD may be configured to generate a composite image that combines the generated first image and the captured second image.Type: GrantFiled: September 7, 2016Date of Patent: March 28, 2017Assignee: Google Inc.Inventors: Richard The, Max Benjamin Braun, Chris McKenzie, Alexander Hanbing Chen

Publication number: 20150358232Abstract: A packet forwarding method and a VXLAN gateway. A VXLAN packet is received. The VXLAN packet includes a communication packet that is sent from a first VM to a second VM; a second VNI of a subnet in which a next-hop device of the communication packet is located is determined according to a first VNI of the VXLAN packet and an IP address of the second VM of the VXLAN packet; the communication packet is encapsulated according to the second VNI; and then an encapsulated VXLAN packet is forwarded to the next-hop device through a tunnel corresponding to the second VNI, to avoid that the VXLAN gateway can implement forwarding of the VXLAN packet only after the VXLAN gateway modifies the communication packet in the payload of the VXLAN packet, and improve efficiency of forwarding the VXLAN packet.Type: ApplicationFiled: August 19, 2015Publication date: December 10, 2015Inventors: Hanbing Chen, Yu Song, Zhiqiang Xiong
